Task not assigned to group (activiti:candidateGroups)

nicolasraoul — Fri, 22 Jun 2012 06:02:57 GMT

The pooled review workflow works fine as long as the first userTask has activiti:candidateGroups="${bpm_groupAssignee.properties.authorityName}".But if I replace with activiti:candidateGroups="PURCHASING_AGENTS" then nobody seems to receive the task.I made sure I have a group called PURCHASING_AGENT

Hello,

it seems you're forgetting the prefix "GROUP_" which is part of the authority name and should be provided.

Hi Axel,
Where should the "GROUP_" be prefixed? I'm facing this same trouble and after reading this post, I have something like this:

candidateGroups="GROUPS_PURCHASING_AGENTS"‍

(borrowing from Nicolas's example) yet it didn't show up.

What am I doing wrong? Where should I append the "GROUP_"?

Yes that is the location it should be placed
activiti:candidateGroups="GROUP_PURCHASING_AGENTS"
are you getting any error in the logs?
Also I hope you are not missing "activiti" prefix before candidateGroups

Thanks for the reply.

I put it there, exactly, yet I don't see the progression. The start-task form is visible and when I start it up, I notice that it is running at the workflow console, but it's not available for the users on that group to claim it.

No error is shown at the log as regards to it. The log is clean. A segment of my bpmn is shown below:

The startEvent works perfectly, but the workflow is not available to users of the group to claim it. As you would observe, I didn't use any custom model for any of them, so I I didn't need to define anything else.

ok there is one more thing you need make sure.
If you are using Alfresco Explorer you need to configure your dashboard to add pooled task dashlet.
and in Share you need to make sure you are checking the pooled tasks list.

Hi erveryone!
I want to assign to a group from my form selection. I use:

Hi Mits

sorry to boder you for a sec please. I have seen your post regarding how to make sure we are assigning a task to an Alfresco Group, and would like to ask you something. We are launching the workflow from a file which has a type with a property called "Departament". The Departament value is the name of the alfresco Groups the workflow needs to assign the task… so now dont know exactly how to specify the group dinamically.

we have tried something like


<userTask id="iniciar" name="Revisar JefeDpto" activiti:candidateGroups="GROUP_test.children[0].properties["hula:department"]" activiti:formKey="wf:activitiReviewTask">
‍‍‍

or something like


<userTask id="iniciar" name="Revisar JefeDpto" activiti:candidateGroups="GROUP_"+${test.children[0].properties["hula:department"]}+" activiti:formKey="wf:activitiReviewTask">
‍‍‍

but it does not work.

Any sugestions about how could we get this property and use it to assign the task to the right group??

Thanks a lot!!

Hello,

you can't do something like this even with expression language. For one, the GROUP_test is just a string and not a feature object you can use to query members from. Secondly, concatination in XML is not a thing and the example with the expression results in invalid XML.

The only way to handle such a use case is to use task listeners (either Java or script) to execute some code when the task is created to set the candidate groups dynamically. Within Java or script you can use the Alfresco (Script) API to lookup particular authorities and iterate over their members.

Axel

[Summary]
When completing a pooled activiti workflow task in Chrome, the user is not redirected back to Dashboard as happening in other browsers.
[Reproduction]
1. Create a "Pooled Review and Approve" workflow task and assign it to your own group.
2. From your dashboard click on the new unassigned task.
3.Claim the task by clicking the "Claim" button
4. Click on "Approve" to complete the task
5. Instead of redirecting the user to dashboard, user stays back in the same edit task page.
[Current Behavior]
After completing the task, user is not redirected to his dashboard but stays on the task property page.
[Expected Behavior]
As in other browsers, user is redirected to his Dashboard.

I can notice that in Firefox I have "GET DASHBOARD" at the end of the operation, and I don't have this "GET" using Chrome. Chrome (working with defect) and Firefox and IE9 (working as expected).
In Chrome Browser, the request header "referrer" is getting changed when user claims the task. It changes from user dashboard url to task url. So it stays back in the same page.
