I'm trying to create a task with a colection for multi insance approvals over some groups. It's an readonly list, so it makes more sense to write it directly on the bpmn xml. I tryed this:<userTask id="aprovarPCMC" name="Aprovar Plano de Curso e Matriz Curricular" activiti:candidateGroups="#{grou

No, i don't think so. That would work on a script task, but not in a JUEL expression. Maybe use a script execution listener just before the multi instance that sets it?

Isn't there an easier solution ?
Some tag where i would set the list like <sourceList>group1,group2,group3</sourceList> ?

If there isn't I'll just create a bean for that.

Also could you provide an example with ScriptTask ?
I'm kind of new at Activiti and also the only one here messing with it !

Thanks

I solved it with Java service task.
For future reference:
<code>
<serviceTask id="generateList" name="name"
             activiti:class="br.com.app.servicetask.ClassName">
         <extensionElements>
         <activiti:field name="values" stringValue="group1,group2" />
      </extensionElements>
     </serviceTask>
</code>

The class just splits the field values and sets it to an variable

A sriptTask would effectively do the same: execution.setVariable('collection', java.util.Arrays.asList('a', 'b'));
