Problem using bpm_groupAssignees

[softbless]

Hi,

I'm developing a workflow that assign to multiple Groups. I'm using variable bpm_groupassignees

But I have some problems when assigning all users in that multiple groups to a variable named : reviewer

This is some of the processdefinition :

<node name="startreview">
        <action class="org.alfresco.repo.workflow.jbpm.ForEachFork">
            <foreach>#{people.getMembers(people.getGroup(bpm_groupAssignees))}</foreach>
            <var>reviewer</var>
        </action>
        <event type="node-enter">
            <script>
                <variable name="wf_approveCount" access="write" />
                <expression>
                    wf_approveCount = 0;
                </expression>
            </script>
        </event>
        <transition name="review" to="review" />
      
    </node>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The log said : "Failed to signal transition null from workflow task jbpm$33……Group is a mandatory parameter"   
   
I've tried to google the workflow that use bpm_groupassignees. But my search give me nothing.

Please help how to assign the reviewer variable for that bpm_groupAssignees, I think it would help many people with similar problem

Dear friend,
Maybe group select is not sub group So

people.getGroup(bpm_groupAssignees)‍

is null Then

people.getMembers(null)‍

throw Exception.

Check all cases. I haven topic for that please search in forum.
Goodluck.
