Hi I have created one workflow in which I am initiating the workflow from admin account but i want to assign the next task to a particular user let say 'abc'.can i do this by adding the following lines in the process definition or do i have to add pooled task tag for assigning the task to the speci

Simple approach could be following:


<task-node name="review">
        <task name="wf:reviewTask">
            <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
               <actor>#{bpm_assignee}</actor>
            </assignment>
        </task>

       …
</task-node>
‍‍‍‍‍‍‍‍‍‍‍

To resolve the variable bpm_assignee, at least you have to set a processvariable on workflow-start (or later by an action or something else that has access to the ExecutionContext of JBPM).

Something like this should work:


 Map<QName, Serializable> params = … 
 params.put(WorkflowModel.ASSOC_ASSIGNEE, "thomas");
 getWorkflowService().startWorkflow(selectedWorkflow, params);

Easiest way, if you want the user whose userName is "abc" to be the swimlane :


<assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
  <actor>abc</actor>
</assignment>

Hello together,

and what's the way to assign three specific groups to three different swimlanes via java api? Is this possible?

Thanks for helping

If you have those swimlanes in your processDefinition.xml :


<swimlane name="Group_1">
          <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
            <pooledactors>#{var_Group_1}</pooledactors>
      </assignment>
    </swimlane>

<swimlane name="Group_1">
          <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
            <pooledactors>#{var_Group_3}</pooledactors>
      </assignment>
    </swimlane>

<swimlane name="Group_3">
          <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
            <pooledactors>#{var_Group_3}</pooledactors>
      </assignment>
    </swimlane>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The following java snippet will set those swimlanes with the suitable groups (for example "GROUP_VALIDATORS", "GROUP_ADMINS", and "GROUP_USERS"):


executionContext.setVariable("var_Group_1", "GROUP_VALIDATORS");
executionContext.setVariable("var_Group_2", "GROUP_ADMINS");
executionContext.setVariable("var_Group_3", "GROUP_USERS");

Swimlanes are defined in processdefinition.xml.

I only have one small question: how will i set/get/define the execution context and where?

You have 2 solutions :
- call a Java class somewhere in your processDefinition… of course, the Java class setting the swimlane X has to be fired before you enter a task having the swimlane X assigned
- put the snippet into an Alfresco script in your processDefinition… same remark

see Jeff Pott's excellent article
http://ecmarchitect.com/archives/2007/11/19/785
It will illustrate both cases

Hi if I understand correctly your requirement then you are trying to call a child workflow from parent workflow right?? For this you can call a java class from your service task. And from this java class you can initiated another workflow. Like this

processEngine.startProcessInstanceByKey("ChildWorkflowProcessId");

and in child workflow you can add n number of assignee groups as per your requirement.
