I usually don't give this permission at my application top-level. Usually I 
give this permission to appropriate users only on the OpenFlow object.

This allows for managing properties on the instances while leaving the 
outside application untouched.

Oh, ok. Remember giving your user roles the "Add Documents, Images, and 
Files" permission. Again, a good place for this permission is the OpenFlow 
object, so that users can add those objects to a process instance.

Yes I'm considering it, but I'll try figure out a possible different solution 
since a like PageTemplates much better than DTML. Anybody can help?

Anyway probably this will be scheduled after some more urgent work.

Sure. I hope you'll want to use the product. =)

I am concerned about side-effects to other objects if a clueless 
zopeadministrator just gives manage_properties to Authenticated-role at the 
toplevel.

Sound OK to me. I'm not sure if manage_addProperty actually is protected with 
"Manage properties".

I was thinking of putting files and images there. Haven't though about custom 
objects yet.

Didn't know it existed until now.

I still have problems with the "View management screens" permission. I hope 
you consider rewriting History.zpt into DTML.

I might be able to contribute some developer resources to this, but we'll have 
to evaluate the product further at EEA first. Everybody is on Easter vacation 
so it will take a while.

[Daniele <d.t...@ic...>]

Hello Soren,

thanks the interface-bug-finding, bug-solving and feature-requesting you sent 
me in your e-mail. And congratulations for your in-depth knowledge in 
OpenFlow and Zope.

About your feature requests:

1) in the applications I realize with OF adding properties is something I do 
to instances any time, not only upon their creation. Usually the roles I 
create for users do have the manage_properties permission to be able to 
create del and change properties. Nevertheless your proposal is definitely 
on-target: it's bothersome having to remember to add this permission to the 
users' role.

What if I overload the manage_addProperty, manage_changeProperties and 
manage_delProperties methods leaving them unchanged but protected by "Use 
OpenFlow" permission (extending your feature request #2)?

On the other hand I often use the process instance as a container for custom 
objects (instances of custom products) that I implement the way I most like, 
allowing them to use whatever method (protected in whatever way I prefer). 
This means that often properties are recorded on these objects rather than on 
the instance itself. This allows for a finer grained permission handling for 
you user roles. But this solving of the issue requires you to build your 
custom product, and this is bothersome anyway, for as simple you make it.

2) reply to feature 2 is included in the solution above, I guess.


Thanks a lot for your effort in making OpenFlow more usable,
	Daniele =)

[Openflow-dev] Re:

[Daniele <d.t...@ic...>]

This error is due to the zope version you are using. You can fix it two ways:

1) move to zope 2.6
2) update your ZCatalog with the most recent version

I'll be fixing this in the cvs version of OpenFlow so that OpenFlow can be installed anyway even though you have a zope older than 2.6.

Should you have further questions you can also mail to the openflow mailing list where other people can help you with their answers.

RE: [Openflow-dev] Getting started with OpenFlow

[Antonio De M. <Ant...@ee...>]

Dear Andrew,

I know your frustration about getting started with Openflow.
Unfortunately there is no workflow demo or tutorial at this time.
there was one once but due to modification of the product's API the demo
does not work anymore. So somebody has to create a new demo for all of them
who still haven't get anything working.

My experience
We at EEA (European Environment Agency) have been looking at openflow. 
After a 2 weeks of deep theory reading, code inspection and direct support
from Daniele we finally understood the machinery behind. And I'll tell you
is quite well done and comparable to other commercial workflow engines
(excluding documentation and tutorial). All of them have their own
limitations of course, no matter what you choose. Workflow engines are one
of the most difficult software to produce. They have to deal with
parallelism, synchronization and deadlock etc .. On the other hand workflow
have to be understandable to humans since they will be the main actors of
the worklfow. Workflow is a way to program people's work, to apply
programming and automation in the way we work daily. That's not always
possible. Workflow patterns try to explain this
http://tmitwww.tm.tue.nl/research/patterns/.

So the workflow engine is there and works fine (for most workflow patterns)

The difficulties are in understanding the machinery of the engine, how to
use the API and the main cycle (from the developer's guide): 

Main cycle
1. addInstance
2. startInstance
3. pullWorklist
4. callApplication
5. activateWorkitem
6. elaboration of activity (the actual task)
7. completeWorkitem
8. for all remaining workitems start from 3 again.

the above is a cycle that continues until no more workitems are left in the
process. Then at the end the whole process would stop.

Openflow is not a simple product that you can plug-in and you can work with
it directly.

In order to start developing with Openflow you have to read the following
documents about workflows.

Openflow documents. 
http://www.openflow.it/Documentation/documentation/

Workflow model
http://www.openflow.it/wwwopenflow/EN/Documentation/workflowdocs_html

Workflow patterns. It gives an overview of the problems in designing
workflow solutions and how to solve them. It also shows which patterns are
unsolvable by many workflow engines. 
http://tmitwww.tm.tue.nl/research/patterns/

Developers manual. That's probably what everybody wants to see.
Unfortunately only in Italian.
http://www.zope.it/Members/rlemmi/manuale_OpenFlow.pdf/view

I will probably put an example on the Zope website as soon it is finished.

Regards and nice reading
Antonio

Hmmmm, the longer I look into 'OpenFlow' and whatever 'OpenFlow' is, 
because it could be www.openflow.it's OpenFlow or OpenFlow_Relflow the 
more confused I get. I understand Daniele that you are trying to help 
and I thank people like yourself for trying to do this (I really do!). 
However the use of this product (which ever one your talking about) 
seems to be shrowded in mystery. Yes there is no support, which is why I 
myself keep posting to this mailing list.

I believe I'm looking at getting OpenFlow (NOT CMFOpenFlow_Relflow) up 
and running for a simple workflow model. After spending a week with the 
product(s) I'm still no further at understanding it than what I was a 
week ago. I'm guessing I need to get the application wizard up and 
running and then the openflow editor. But as I say again, the use of 
these products is simply a mystery.

No one actually describes how to use the product, just how to install 
it. There is probably a lot more people than myself who would love an 
example or explaination (no matter how small the example) of how to 
build a workflow model and how to get some kind of output from this. 
This is (for myself anyway) the critical information needed to use the 
application.

I don't mind documenting my discoveries as I go for others to use. I can 
do this and post it via the list, however I really require some of you 
guys out there (who know how to use it) to help me.



Sorry about all the bitching, and thanks for reading my post.

product(s) I'm still no further at understanding it than what I was a 
week ago. I'm guessing I need to get the application wizard up and 
running and then the openflow editor. But as I say again, the use of 
these products is simply a mystery.

No one actually describes how to use the product, just how to install 
it. There is probably a lot more people than myself who would love an 
example or explaination (no matter how small the example) of how to 
build a workflow model and how to get some kind of output from this. 
This is (for myself anyway) the critical information needed to use the 
application.

I don't mind documenting my discoveries as I go for others to use. I can 
do this and post it via the list, however I really require some of you 
guys out there (who know how to use it) to help me.



Sorry about all the bitching, and thanks for reading my post.

Re: [Openflow-dev] monitoring tool for OpenFlow

[Daniele <d.t...@ic...>]

Hello Andrea,

I'm glad you are developing on the OpenFlow tools. The Instance Monitor is 
something we planned on doing and I would like to thank you since you want to 
be developing it.

For the requirements I don't have any yet: I trust your judgement. When I'll 
have some I'll let you know. 

The only point I would like to rise is about product differentiation: I would 
suggest you to make this tool a different tool from the Process Editor. I 
would go with an Instance Monitor product, a totally different product. 

This way you could use different tools for different tasks. Process Editor 
takes care of designing the process (design-time activity), while the 
Instance Monitor graphs the flow of the instances (a run-time activity).

What do you think about this?


Cheers,
	Daniele =)

Re: [Openflow-dev] Getting started with OpenFlow

[Daniele <d.t...@ic...>]

Hello Johan,

OpenFlow and CMF OpwnFlow are two different packages. Please refer to 
www.openflow.it for OpenFlow and www.reflab.it for CMFOpenFlow.

Since I don't feel confident with CMFOpenFlow (I don't know enough about it 
and there are other people taking care of it) I'll be talking about OpenFlow. 
Latest release version of OpenFlow is 1.0.6 so it seems you have the right 
one.

You get the mentioned error because your ZCatalog doesen't have the 
CatalogPathAwareness library. If you switch to Zope 2.6.0 you'll get it by 
default. Or you can try downloading just the latest ZCatalog product.

CMF is not needed for OpenFlow. It should not hurt you either having it or 
not having it installed.

I know documentation about OpenFlow is scarce. And often outdated. I hope 
somebody in the community could help with their experience in using OpenFlow. 
Otherwis you'll have to wait 'till we get it written down. Sorry.

Cheers,
	Daniele =)

[Openflow-dev] Getting started with OpenFlow

[Braeken J. <Joh...@op...>]

Hi,
=20
I'm having trouble getting started with OpenFlow.
I hate to say this, but the documentation of OpenFlow is rather bad. :-(
=20
What version of OpenFlow do I need?
Is in on openflow.it or on reflab.it?
Or is CMF OpenFlow (now Reflow) a totally different package?
=20
What do I need?
I have zope on Linux.
Do I need CMF? I thought I read it somewhere so I installed in anyway.
Are there other things I need? (Plone, ...)
=20
Currently I have:
Linux version: Red Hat 9
CMF 1.1
Zope Version  (Zope 2.5.0 (binary release, python 2.1, linux2-x86),
python 2.1.2, linux2) =20
Python Version  2.1.2 (#1, Jan 25 2002, 13:17:56) [GCC 2.7.2.3] =20
System Platform  linux2=20
=20
=20
When I unpack OpenFlow 1.0.6 and place it in my lib/python/Products
directory.
I get a broken package in Zope:
=20
----------------------------------------------------
OpenFlow (Broken product OpenFlow)
=20
Traceback (most recent call last):

----------------------------------------------------

When I use Reflow 1.0.9 and I follow the procedure explained in
install.txt (Adding an external method) I get the following Zope error:
=20
----------------------------------------------------
Error Type: ImportError
Error Value: cannot import name CatalogPathAware
----------------------------------------------------
=20
So both errors are about CatalogPathAware. What do I do about it?
I think I need a package I don't have...
=20
I'm also new to Zope, but I familiarized myself to it in the past few
days.
=20
=20
Kind regards,

[Openflow-dev] monitoring tool for OpenFlow

[<And...@we...>]

Hello Daniele,

in the near future I want to write my degree dissertation. So I experienced with OpenFlow and OpenFlow Editor. Hannes Vogt told me that you are interested in a monitoring tool for OpenFlow.

Yesterday I started to program some enhancements for the Editor Tool, so that you can map an instance of a process (states of the workitems) and the path (transitions) the instance has used.

Do you have some other ideas for requirements? 

Thanks, Andrea.

[Openflow-dev] OpenFlow Application Wizard and Editor

[Andrew H. - L. <ah...@li...>]

Is there a manual or tutorial for the OpenFlow application wizard?
If there is not could someone please take the time to tell me how to use 
this product?
For instance how do I create a workflow and use it in this application? 
and what are the Wizard features?

It would be nice if there was a tutorial (similar to the Zope tutorial) 
but I'm not going to complain (just like your not taking my money!) but 
it would be nice.

I'm also going to try and get the Zope Editor working (if I can get my 
mandrake libaries under control, they are giving me grief too!). If 
anyone can help me with this I'd be very thankful.


So if any of you could take the time I'd love some help!!!!!!
You can reach me here -->  ahughes @lisasoft.com  <---- there's a space 
in there you'll need to remove.


Anyway, my compliments, everything looks excellent. I just wish I knew 
how to use it.

[Openflow-dev] Re: some question about Openworkflow

[Daniele <d.t...@ic...>]

Hello Gao Juntao,

I'm glad to see you are interested in OpenFlow, and that you are thinking 
about moving your interest to help us developing it. Since you don't seem to 
like the meta model so much, do you have suggestions for the workflow meta 
model? Let me know what would you like to develop for OpenFlow and how: 
you'll be welcomed on board.

There is a mailing list for openflow used by developers (as well as newborns, 
actually). I'm mailing this reply to the list as well: everybody will be glad 
to know one more person is interested in the development. Would you mind 
mailing the suggestions there as well? You can subscribe (if you still 
haven't) at:
http://lists.sourceforge.net/lists/listinfo/openflow-dev


Cheers,
	Daniele =)

Re: [Openflow-dev] Show instances with Openfloweditor?

[Daniele <d.t...@ic...>]

Hello Hannes,

it is definitely possible and we were already planning to be making it! 
Although, this will not be implemented in the OpenFlow Editor product: we 
wanted to create a different product for doing this (OpenFlow Instance 
Monitor, perhaps?).

If you feel like you might be wanting to develop it yourself do let us know: 
we'll include it in the OpenFlow products (if you want).

Thanks for suggesting
	Daniele =)

[Openflow-dev] Show instances with Openfloweditor?

[Hannes V. <Vo...@dr...>]

Hi

I've a little question about the Openflow editor. Will it be possible to
show not only the processdefinitions but also the instances of processes in
a later version? To better understand me: My plan was it to show the user
the instance in which he is actually working. He should see which activity
is the workitem, which is completed, which is not even touched and so on.
If something like that is planned, please let me know.

Thanks Hannes

Andrew -

Many if not most of the answers you are looking for are long and not
something that would be answered in a day.  Let me ask in return, how
familiar are you with Zope and Python?  From your questions, I would guess
you are also pretty new to Zope as well.

In basic terms, anything logical can be done by the
Zope/Plone/CMS/OpenFlow/Python/SQL db of your choice.  OpenFlow is a Zope
product that is a part of the large product and features of Zope and is
extended by programmers using Python and database functionality.  Of course,
Zope has it's own database, so using an add-on database is a decision based
your needs and the availability of adapters.  There are adapters for most
major databases, both proprietary and open source.

Some of what you are asking for comes from functionality in Zope and the
portal product you chose, not OpenFlow itself.  User management as an
example is best done as a local function in Zope but if you don't know how
Zope works, it is a long discussion to understand how flexible the user
management actually is.  Plone, CMF, and some of the other less well-known
portal products for Zope have levels of user management you are asking for
above and beyond what Zope itself provides.  There are also products that
can be added to add more levels of user management or the facilities that
exist can often be extended by a Python routine crafted to pull information
from Zope and customize it to what you are looking for.

What OpenFlow is not is a stand alone product at the level of Ultimus or
some of the other proprietary workflows.  But in all honesty, those products
depend on knowledge of things like the Microsoft Transaction Server and IIS.
Instead, it adds additional workflow features to Zope and its product set.
I say additional, because workflow and the concept of divided
responsibilities/roles is a basic feature of the Zope concept for
application development, maintenance and user interaction.  To understand
what OpenFlow adds, you need to understand Zope and the products you are
using with OpenFlow and that isn't exactly simple.

Because of that, mapping an application for this system requires an
understanding of what each Zope product can do natively and when
functionality is best used as it exists and when it is time to built a
Python routine to add what you need.

To me, and no offense intended I assure you, it sounds like you need to
start by planning what your system needs to do and not by a feature set that
might compare with a proprietary solution but may or may not be actually
used.  Then you need to break down the system to display, data, and
functionality and implement each level in the products that meet the needs.
I doubt I would be wrong by saying all of us have had to do that to figure
out Zope.  It does take time and the help to make it happen is weaker than
it should be, but because of the object-oriented nature of Zope, the benefit
is the smallest widget you build can be reused multiple times.

So, if I failed to answer your questions with direct answers, it is because
there are multiple approaches to every requirement you mention and no right
way at a generic level.  To make it work, start small, move your way through
it one step at a time.

So much for the "short" answer...

Regards

Mike

[Openflow-dev] A few quick questions.... please help me out.

[Andrew H. <ah...@li...>]

Hi I need some help with some questions answered (and very quickly too 
I'm stress'n).

I'm very new to OpenFlow, and a client wishing to access its 
capabilities has a few questions they need answered by the end of the 
day..... please help me if you can. My answers need not be more than one 
or two scentences, and in some cases and Yes or No will do the job.

Any help would be fantasic.....

    * Can reports be generated in HTML and delimited format for use with
      MS Excel?
    * Does the WMS interface to an external report writer? If so, state
      which, and describe how the interface is effected.
    * Can employee attendance and log-on activity be tracked?
    * Can employees be tracked for various processes they supervise?
    * Can activity reports be generated by employee group and profiled
      against other groups?
    * Can the history of all transactions be maintained?
    * Can processes be flagged inactive or cancelled but retained
      for later use or revision?
    * What facilities are available to track resources, including staff
      & equipment?
    * Is there capability for conflict resolution when multiple needs
      are placed on individuals or resources?
    * Is there capability for planning and forecasting?
    * Can checklists be generated?
    * Can calendar changes be made which reflect a range of delivery areas?
    * Can e-mail be linked to notification of events and completion of
      activities etc? If so, describe how .
    * Can any number of customisable e-mails be created?
    * Can Zope be configured with Oracle (prefered) / SQL Server?
    * Is there capability to import and export data ? Is the import /
      export format customisable ? Specify the formats catered for


Any feedback would be extremely valuble!!! And I would be very thankful.


Thanks in advance,

Re: [Openflow-dev] Problem with OpenFlow editor 0.3.2

[Daniele <d.t...@ic...>]

Well, 

you're right again =). The missing file is nothing much really: it is just a spike I made to see if I could change the activities shape in the graph.

Still it might be handy so there, I posted the complete version: OpenFlow editor 0.3.2. 

I now have a script checking that all cvs files are released. Thank you.

Cheers,
	Daniele =)

[Openflow-dev] Problem with OpenFlow editor 0.3.1

[<And...@we...>]

Hello Daniele,

I think you forgot to upload another file. In source code I found this:

    browse_workflow = PageTemplateFile('zpt/browse_workflow', globals())
    graph_settings = PageTemplateFile('zpt/graph_settings', globals())
    edit_process = PageTemplateFile('zpt/edit_process', globals())

But I can't find the "graph_settings.zpt".

Thanks, Andrea.

[Openflow-dev] Re: Re: RE: OpenFlow editor 0.3

[Andrea S. <And...@we...>]

Hello again,

ok, it works, but now I've another problem:
If I want to "see" my Process, I always get a blank screen without the image. The "edit_process.zpt" works (the map and the form operate), but I can't see the picture of the process. The "infile" and "outfile" are created, but there's the outfile not blank.
Can you help?

Thanks, Andrea.

Re: [Openflow-dev] RE: OpenFlow editor 0.3

[Daniele <d.t...@ic...>]

Right,

I forgot to cvs-add the file so when I extracted the tarball the file was not there.

I added the file and released the OpenFlowEditor 0.3.1

Thanks for your feedback on this (and thanks to Roberto Borgotallo for raising the same issue)

Cheers,

Hello,

I'm glad to see that there's a new version of the OpenFlowEditor, but when I test it, ZOPE can't find the "edit_process.zpt" (in Folder "./OpenFlowEditor/zpt/" exists "browse_workflow.zpt" only).

Thanks, Andrea.

Francesco,

Yes, that fixed it.  (I grabbed the 1.0.9) from
http://www.reflab.it/community/Openprojects/CMFOpenflow/ and it is working
great.  Thank You!

Is there any help that I can provide with documentation?  Who should I speak
to?  Although I don't speak Italian, I can provide documentation in English
and with my Wife's help, Spanish.

Some areas that I can contribute:

Examples for using Openflow/Reflow.
Proofreading.
Making pretty/standardizing.

Cheers,

Timothy Cole

Hi, 

yes, there was a problem with catalog using Zope 2.6.1 ....
the good news is that it as been fixed (some weeks ago in cvs) together with

other minor bugs; the "bad" news is that the you have to download it from

I will also update the tar (Package), I promise! :)
