--------------------------------------------------------------
I am successfully using jPDL with an AssignmentHandler to programatically assign a task.

    <task name="review" >
        <assignment-handler class="mypackage.AssignBySomeRule">
            <field name="ruleName">
                <string value="exampleAssignmentRuleName" />
            </field>
        </assignment-handler>    
        <transition to="approval" />
    </task>

Is it possible to accomplish this with BPMN? I know there is a "resourceAssignmentExpression", but it isn't clear that this can do the same thing.

  <userTask id="myTask" name="My task">
    <potentialOwner resourceRef="manager" jbpm:type="group">
      <resourceAssignmentExpression>
        <formalExpression>management</formalExpression>
      </resourceAssignmentExpression>
    </potentialOwner>
  </userTask>

Can the "formalExpression" invoke arbitrary java classes or does it need to use process variables to evaluate to a user or group name? 

Thanks!
