Parallel & Pooled Workflow

lementree — Mon, 06 Aug 2012 08:50:38 GMT

HiI want to define a Review/Approve workflow.Where the Reviewers are from Different Groups.So I want to start Review workflow parallel to All the groups, then any one of the user from that group will approve/reject the workflow.Can please any one tell me Processdefinition using BPM Activity.If even

Have you already read the first edition of the advanced workflows tutorial? It shows how to do a workflow with multiple pooled groups.

Hi Jeff,

Thanks for your response,

In that example Marketing and Engineering Reviewes are Pre-Defined groups.

But here the groups are selected from UI using (bpm_groupAssignees). I want start parallel and pooled review task for each group they selected dynamically.

Please help me.

Thanks & Regards

The group selection example is out-of-the-box. Go look at the parallelreview_group_processdefinition.xml in $TOMCAT_HOME/webapps/alfresco/WEB-INF/classes/alfresco/workflow.

Hi Jeff,

Sorry for My English.

I think you not understood my Issue Clearly.

My Requirement is as below:

For example I am having Multiple groups as Group1 to Group 10
Then In the Workflow I will choose few groups from available groups to Startworkflow.
Then the review Task should be Parallel for all selected groups, One of the pooled user from the each group will approve/reject the Task. ‍‍‍

In the Example you gave in the last post is dealing with the same, but in Process Definition The Groups Names(Marketing & Engineering) are hard coded but I want those group names should be Dynamically get from selected groups. I.e I want to start parallel Review for Each group in groupAssignees.

Thanks & Regards

I think what you are looking to do is very similar to that process definition. In your case, instead of iterating over the members in the group, you are going to start a task for each group in the list of selected groups, and make sure that you are using a pooled assignment for each of the tasks you spawn.
