[Openflow-dev] Add Transition Problem

[Nikos P. <pa...@fr...>]

Hi to all of you,

I am using OpenFlow 1.2.0 for the last month (Zope-2.6.1). Great Product.

I noticed a small bug when I create a new transition. The description 
attribute is not saved.

I have to change transition attributes and then the description is saved 
properly.

Does anyone have the same problem?

Nikos Papagrigoriou.

Dear Haroun,

I would suggest you install the DocFinderEverywhere product. Once installed 
it will automatically find all classes and methods of any Zope object you 
instantiate, giving you a "Doc" tab in each item manage view. You'll find it 
at:

http://www.zope.org/Members/shh/DocFinderEverywhere


Cheers,
	Daniele

This ends the handling if the exceptional workitem.

This creates new workitems (yes, even more than one if called more than once) 
in any activity of the workflow. 

So this brings to the following handling example:

A workitem (say 1) in activity A goes in exceptional state (fallout). You can 
take it resume its course in activity B (workitem 2) and C (workitem 3) 
calling the fallin API twice, once specifying B and once specifying C 
(thereby creating a parallel flow). To signal the ending of the exceptional 
state you call the end-fallout API: workitem 1 will cease being exceptional 
and thereby can't generate any new workitem. Flow will resume from activities 
B and C (the instance being "alive" and running with workitems 2 and 3).

This means, in general:

- workitem goes fallout
- resume workitem as many times and wherever you want using fallin
- end the handling signaling an end-fallout

[Openflow-dev] Exception Handling

[Mikel L. <lar...@ei...>]

Hi:

How does exception handling work in OpenFlow?
I'm trying to understand it but I can't ;)

When I fallout a workitem I have 2 possibilities:
   - End Fallout: Is this to recover workitem's original status in the 
activity it was before de fallout?
   - Fallin: With this I can put the workitem in the activity I want, 
but it creates a new workitem? :S What happens with the "original" one? 
It seems to be still in fallout, but then can it follow the "original" way?

I was a little too simplistic in my description.

The Consumer role is to be assigned to an automatic activity, not a
human -- even Producer aren't human, but this doesn't matter, now.

Problem is, Consumer should "treat" jobs arriving to it, but only one at
a time, so it should check for the availability of some sort of
"resource" to become available.
Jobs should wait until this resouce became available, and get "consumed"
in turn.

I would even like to implement some sort of priority mechanism, so jobs
to be processed next are chosen considering their priority.

I hope to having made things clearer now.

Thank you for your interest

[Openflow-dev] Possible status for workitems.

[Tim U. <ti...@di...>]

Is there a list someplace that shows what the possible status of workitems 
are? I know there is active, inactive and fallout but what other possible 
statuses are there.

Also maybe somebody can answer a stupid zope question for me.

I want to query the catalog on a != basis but zope does not like it.   For 
example
<tal:define="workitems python:openflow.Catalog(meta_type='Workitem', 
process_id='hazmat',  status !=' fallout' ,activity_id='Approve')">

[Openflow-dev] serializing jobs

[Guido N. <gn...@li...>]

I would like the advice of experienced Openflow users: I need help in
evaluating the feasibility of this kind of solution:

I want to modelize a rather typical producer/consumer schema.
Actually, there are multiple producers, and a single consumer.
The consumer should "treat" the accumulated jobs one at a time, making use
of a single resource.

In other words, multiple jobs, arriving maybe in parallel, should be
"serialized".

I wonder if it's possible to model such a thing in Openflow's
implementation of a workflow.

Thank you of any suggestion

ciao
Guido

That's pretty much what I did.  It worked out OK.

   I think you should get first instances from catalog and ask them 
whether they have the property you want. Something like this:

wf = context.Workflow
cat = wf.Catalog
insts = cat(meta_type='Instance')
for ins in insts:
     if ins.hasProperty('this_one'):
	# Stuff1
     elif ins.hasProperty('other_one'):
	# Stuff2

	# Stuff3

Thanks for the tip, this worked great.  This works great for searching on 
top level attributes but can you tell me how I might search for attributes 
of the workitem itself. As the instance travels through the workflow I add 
attributes to it using the instance.manage_addProperty api and I'd like to 
query for workitems which have a certain property.

Thanks again.

[Openflow-dev] Application Wizard (again)

[Mikel L. <lar...@ei...>]

Hi!

I'm testing OpenFlow Application Wizard and I had to modify source code 
in order to run it.

These are the changes:

->application.py
222: worklists_folder = getattr(self.aq_parent, 'Worklists',None)
223: if worklist_folder and ('worklist' in ...)
		^
                 |
There was a mistake, it must be: if worklists_folder and ....

->operation.py
Here, I got 'AttributeError' when calling
     instance = getattr(openflow, instance_id)
in function runOperation and I changed it:
     instance = openflow.getInstance(instance_id)

Now it seems to work correctly.

Best regards

Try getting workitem info from catalog:

# If you want to get only workitems that are active or inactive, you
# should do: wis = cat(meta_type='Workitem', status=['inactive']) or
# status=['active'], ... or if you want to get workitems assigned to
# an user add actor='your-user-name' or
# actor=AUTHENTICATED_USER.getUserName()
wis = cat(meta_type='Workitem')

And then:

for wi in wis:
     # Get the instance_id
     i_id = wi.instance_id
     # Get the workitem_id
     w_id = wi.id

This goes in a python script. If you want to have it in a ZPT, you can 
see Demos.zexp examples at OpenFlow site:
http://www.openflow.it/EN/Download/index_html
and see workitem_html file in Forms folder

[Openflow-dev] (no subject)

[Tim U. <ti...@di...>]

Hello all.

I have been trying to implement a very simple workflow for demonstration 
purposes. What I want to do is the following.

1) User A fills out a form and enters information about user B.
2) The application then creates user B in zope, assigns the user to the 
proper group, initiates a workflow and then asigns the task to user B.

I have created a application using the ticket tracking example and can 
initiate a workflow but I don't know how to get the workitem_id so I can 
assign it to the user.

Can anybody help me.

Well, I found a way to link applications and activities, but...

I can only link those applications which are "automatic". I can create
an automatic application without operations and I can link it, but not
if it has operations.

Hi !


I'm testing OpenFlow Application Wizard but I can't make it run. I
create applications to link with Activities but when I want to link them
there is nothing in the combobox where I should select the application.

I've created some applications and add them some operations, but I can't
link them to activities.

Formulator product is properly installed.

Any idea?

[Openflow-dev] Bug and Patch in OpenFlowEditor for Win

[Sebastian K. <seb...@gm...>]

Hi openflowers,

OpenFlowEditor doesn't work on Win for some reasons:
1. Win is very particular in reading from binary files and showing the
binary data (result = out.read())
2. mktemp seem to work not relliably on Win (shows abreviated foldernames
(myFol~/anotherFo~/) at least on my machine)
3. The install_path of graphviz on Win machines is different to the
unix-standard

The following patch solves all this and works at least on my Win-box as
expected, when placed in a file Products/OpenFlow/EditorWinPatch/_init_.py
1. if Win it sets binary-data-reading and showing
2. it generates a temp_filename from DateTime()
3. it allows to configure the install path with the variable:
dot_install_path

I hope this helps other Win-users to enjoy this nice tool like I do,

[Openflow-dev] multiple from applications of transition objects

[Sebastian K. <seb...@gm...>]

Hi openflowers,

I like your product a lot, thanks for developing it.
I have a question concerning transition objects.
A transition needs a certain, well definded target activity object (to
activity).
But wouldn't it be more flexible, more easy to manage and substancially
reducing the amount of transition-objects
if the from activity object would allow multiple entries (by a multiple
selection in the from dropdown list)?

Or is there a reason for just allowing one?

Thanks for your oppinions, SK

[Openflow-dev] Bug in openflow: showing properties of workflow_items?

[Elena S. <ele...@gm...>]

Hi,

in a python script I try to get the properties of a workflow_item object. I
can get them except the ones of the last one in
wf_obj.objectValues(['Instance']).
The last one shows only the title property. If I add another workflow_item,
the previous item shows its properties perfectly. It seems to be a bug.

wf_obj=getattr(context, openflow_id)
last_inst_prop =wf_obj.objectValues(['Instance'])[-1].propertyIds() <-------
shows only the title property
bef_last_inst_prop =wf_obj.objectValues(['Instance'])[-2].propertyIds()
<------ shows all properties as expected

-- Can somebody give some clues about that, Thanks Elena

I guess some people must have done this already, as a timer is an essential

Could anybody show an example of this?

Sorry, 

cron jobs are the only solution that comes to my mind. I'm not too confident 
with cron... still the following can be some guidelines to solving your 
problem.

Set your cron in an automatic activity before the activity you want to 
monitor (with an external method, I presume). Let your cron trigger an http 
request to your script of choice (you might want to trigger a given 
transition with this script so that the workitem goes somewhere you want it 
to go upon reaching its deadline).

[Openflow-dev] auto time alert on workflow activities

[Elena S. <ele...@gm...>]

Hi,

what is the best way of implementing a auto time alert on workflow
activities? E.g. a certain activity has to be executed after a given time
has elapsed without an action of a user concerning a task on his worksheet.
(Is there an alternative to cron-jobs?)
