Hi Luca,

this sounds great.

Wow,

this seems to be great news, since  one of the ides for upcoming OpenFlow 
development is to have customizable storage for openflow objects!

  Hi,

Subject: [Zope-Annce] AdaptableStorage: Object-Relational Mapping for ZODB

The first alpha release of AdaptableStorage is ready.  AdaptableStorage
lets you store ZODB objects in your own database and in your format,
without using special content classes.  You can use a filesystem
directory, a relational database, or whatever kind of database you might
have as a ZODB.

This is very different from all previous solutions.  LocalFS, ExtFile,
CMF directory views, and other similar products require you to use
special content classes that store themselves outside the ZODB.
OracleStorage and CVSFile store all objects as pickles.  Other solutions
have similar issues.  AdaptableStorage, however, reuses as much of ZODB
as possible to achieve orthogonal persistence to arbitrary databases and
formats.

At this time, AdaptableStorage comes with two default mappings, a
Zope2-filesystem mapping and a Zope2-PostgreSQL mapping.  These mappings
demonstrate AdaptableStorage and provide a pattern for creating your own
mappings.

Version 0.4 is an alpha release. There is enough documentation to get
started.  You will need to download version 1.0.2 of the DBTab product,
also released today.

[Openflow-dev] OpenFlow 1.0.3

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

Dear OpenFlowers,

in the download pages of the openflow site you will find OpenFlow version 
1.0.3.

Changes include fixing for using OpenFlow on zope 2.6.0 (ZCatalog is set up 
in a different way) and some minor changes on zpt interface.

Special thanks a lot to Sven Kramer, Adrian van den Dries for their support.

Daniele Tarini - Icube

Re: [Openflow-dev] Windows2000/Linux RedHat import problem

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

The problem you get might be caused by a simple mis-naming of the OpenFlow 
directory. Look in your lib/python/Products directory and check out the 
OpenFlow directory name.

It seems that in your previous Zope installation the directory was named 
"openflow-engine", while now it is named some other way (maybe "OpenFlow"?) 
Name the directory the same way you had in your previsous Zope installation 
and restart Zope.

If it still doesn't work write again and we'll try finding a solution.

Regards,
  Daniele =)

Dear Jim,

the demo you have was for OpenFlow 0.7.2 

Right now there is no such demo for the current OpenFlow (version 1.0 
onward): I had hoped to be able to sketch one but I still could not find the 
time to do it. 

It's one of my "to do". As soon as I sketch it out I'll warn you with a mail 
on this list.

[Openflow-dev] Windows2000/Linux RedHat import problem

[sophie s. <sei...@sy...>]

Hi,

I work for the EADS Sycomore company in France.
I am doing tests on OpenFlow to integrate it on one of our customer's 
platform.

I have an import problem :
I have developed a workflow with Zope/OpenFlow on Windows 2000.
Now, I work on RedHat8.0.
I have installed Zope and OpenFlow on Linux RedHat8.0 and I would like 
to import the workflow I have done on Windows 2000.
I did an export on Windows 2000, and I try to make an import on 
RedHat8.0, but I have the following problem :

2002-12-17T11:42:45 PROBLEM(100) ZODB Could not import class 'openflow' 
from module 'Products.openflow-engine.openflow'

All the DTML documents are correctly imported, only the openflow object 
is "broken".

I think I have installed OpenFlow correctly because I can create 
openflow object from the Zope manage page...

Could you help me ?
or
Where can I find help ?

Thanks for your help.

[Openflow-dev] Newbie question about the openflow demo

[Jim L. <je...@vz...>]

Hi Openflowers
We really need some help here with this demo.
 
We have very simple questions.
Will someone please answer these simple questions and save us more days
of frustration trying to figure this out.
 
 
We have installed Zope 2.6 and openflow 1.2
We imported the Demo_english zexp
 
Under the Demo_english folder is an acl_users folder with the 9 users
 
How do you log into the system as one of them since they don't exist at
the outer most level.  Have we missed some importing steps.
 
How do you run this openflow demo.  Has anyone successfully installed
and run it.
 
I realize that the demo has been removed from the site, so can someone
say to me:
 
Yes it still works or no it doesn't work.
 
We are very willing to dig to understand the technology but we can't
even get to the most basic parts of this demo.
 
Any help at all will be greatly appreciated and help us get on the way
with this technology.
 
thanks in advance
 
Jim

[Openflow-dev] FW: Need help with Openflow Demo, can't login as any of the users

[Jeff M. <mar...@ch...>]

Thanks in advance for any help. 
First: I noticed that the Openflow demo that existed in .72 version isn't
there anymore, so maybe it doesn't work with the 1.2 code base. 
Anyway Here is what I have done. 
Installed the 2.6 Zope on RedHat Linux 7.3 
Installed Openflow 1.2 
Placed demo in the imports directory 
From the import/export screen imported the demo letting the ownership remain
as it is. 
I now have a folder "Demo_english" with various sub folders. 
There is an acl_users sub folder with all the users. 
They don't exist at the higher (parent level) acl_users level. 
Ok, Now I exited my browser and removed the cookies. 
Brought the browser up, and entered the management screen and tried to log
on as one of the users (I tried all of them). 
As an example, I tried user:alex, pwd: alex 
I immediately get "Authentication Failed! Do you want to retry?" 
Am I missing some fundamental import steps. 
thanks for any help

[Openflow-dev] Applications.zpt bug, and CVS

[Adrian v. d. D. <ad...@fl...>]

Hello.

I notice this bug on line 32 of zpt/openflow/Applications.zpt::

  <input type="checkbox" name="app_ids:list" value="name"
         tal:attributes="name applications/name; value applications/name"/>

(reformatted for clarity)

Overriding the name attribute stops deleteApplication() from working.
The name="app_ids:list" is correct.

Also, the 1.0.2 release version of openflow.py includes a try/except
block for importing CMFCore.Expression, but this check isn't in CVS.

(This should do 'except ImportError', btw)

Why are releases including code not in CVS?

Actually the expression you write has to be a TAL expression (like in page 
templates). So you need precede your condition with"python:" like in:

python: instance.gothere=='left'

I hope this helps.

[Openflow-dev] "Xor split" feature with Openflow 1.0.2

[<bor...@ya...>]

Hello

 

I am currently doing some experiment with the new Openflow version 1.0.2 and I've discovered that the feature "xor split" doesn't work at all. I have manually created an instance, then added the attribute I decided to call "gothere" assigning for example the value "left".

On the process schema I have created of course an activity, say "Activity_A" with xor split enabled and 2 different transactions coming out with conditions : instance.gothere=='left' and instance.gothere=='right' going towards activities "Activity_B" and "Activity_C". 

Proceeding with the flow of the instance I get the error message :

<Zope has encountered an error while publishing this resource.Error Type: CompilerError Error Value: Invalid variable name "instance.gothere=='left'" >

I tried instead with the old OpenFlow version 0.7.2 and it works well, Could someone tell me if is there a work-around or is definitively a bug of this release ?

Thanks in advance

Regards

Roberto

Nope. We trust in ZCatalog: it should be able to efficiently index such 
number of objects. Afterall none of the store objects have full-text indexes.

Yes. 

The indexed objects are all of the openflow objects: processes, activities, 
transitions, instances and workitems. If you want just one kind of object you 
should discriminate using the 'meta_type' index.

Probably someone can help you better than me. Still, if with 
"transactionality model" you mean you are worried about the 'rollback' on the 
ZODB transaction then rejoice: ZODB is fully transactional and any operation 
being aborted (intentionally or for some mishap including zope errors) 
cancels any ZODB changes of the current transaction.

[Openflow-dev] OpenFlow searching.

[Tommaso C. <ke...@ti...>]

Hi all,

I understand that OpenFlow uses the ZODB storage facility
in order to store permanent workflow data.

As I don't know how the ZODB works, I'm just wondering
about what could happen in case of a great number of
process instances going on in the system. Did you ever
test OpenFlow with some thousand of instances ?

As far as I can understand from a very fast look at the
code, the Catalog object inside openflow is sometimes
used to find objects. Is this a way of dealing with
the just cited issue ? If yes, what are the index-ed
items inside the catalog (process definition ids,
activity ids, ... ??).

Do you know what kind of transactionality model is enforced
within the ZODB (when used in the Zope default mode, I've read
you can put ZODB above an external DBMS) ?

Thanks, bye,

	T.

If an activity is pushable by a role it means that users having the role are 
allowed to assign work pending on the activity to other users.

If an activity is pullable by a role it means that users having the role can 
start the activity application to take care of work pending on the activity.

You can use the two functions in openflow.py: 
editActivitiesPushableOnRole(role, process, activities=[], REQUEST=[])
editActivitiesPullableOnRole(role, process, activities=[], REQUEST=[])


Write again should you need more help,

[Openflow-dev] Re: Fwd: OpenFlow

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

Dear Digna,

I just checked the openflow.1.0.2.tgz available for download and I got no 
problem. Maybe you were unlucky (maybe the zope server was down).

About the application wizard: it's a tool for designing common activity 
applications. 

You create a wizard in the same folder where you have an OpenFlow. The wizard 
will allow you to design applications for the openflow: each application will 
be created as a simple sequence of common operations: storing a variable in 
the process instance (creating a property), making an SQL query, sending an 
e-mail and so on. Each operation can be configured to get input from a lot of 
sources: from a form driven by the user, from a SQL query, from some variable 
you set and so on. 

I tried writing the wizard interfaces so that you can get hints on what you 
can do with it. 

Ah, of course you need an openflow installed and created to use the wizard.

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

Dear M.Sayamon,

1) the version you see on www.openflow.it is version 1.0.2: the version file 
was not updated (thanks for pointing out)

2) From your error log I can see OpenFlow can't find the CatalogPathAware 
class. Do you have a lib/python/Products/ZCatalog/CatalogPathAwareness.py 
file? Does it have a CatalogPathAware class?

3) Yes you can have both OpenFlow 0.7.2 and OpenFlow 1.0.2 on the same zope. 
They will have the same meta_type, though. So when you create an OpenFlow 
somewhere on zope you'll have to be sure which one you are creating (when you 
create one look at the html to see what it points to). I do use both OpenFlow 
on my machine, if you need further help just ask.


Daniele =)

Can someone submit an example of an application build with Openflow? 
Thanks. We could bild a library with that examples :)

Daniele,

  #1 worked!

  As I am exploring OpenFlow now, could you tell me or point me to a
convenient reference specifying OpenFlow's transition condition? I am
presented with a text-input field (with no hints) along with from- and to-
selectors.

  I am willing to add what you tell me to a convenient place on the
OpenFlow documentation wiki.

Thanks,

Andrew

[Andrew Ho <ah...@su...>]

Hi Daniele,
  Thanks! I will try it.
  However, I do have CMF installed - I see CMFCore 1.2 listed in my
control-panel-Products. I also have CMFPlone 1.0beta1.

Best regards,

Andrew

[Openflow-dev] Openflow 1.0.2

[Daniele T. <da...@in...>]

Dear OpenFlow-ers,

since the release of OpenFlow 1.0 a few bugs have been reported (many thanks
to Andrew Ho, Swen Kramer and Popescu Dan).

At http://www.openflow.it you will find OpenFlow version 1.0.2 including the
pathces for:

* fixing a screw-up on the CMF workaround (since CMF is not necessary for
OpenFlow)

* fixing dtml for activity add/edit


best regards,
    Daniele =)
