Actually, I think one day I also might want to start a task as soon as one assigns it to oneself, and show the appropriate page right away. In the DVD Store example the following is used:
<h:dataTable value="#{pooledTaskInstanceList}" var="task">
  |     :
  |     <s:button action="#{pooledTask.assignToCurrentActor}"
  |         taskInstance="#{task}" value="Assign"/>
  |     :
  | </h:dataTable>

After clicking the button above, the new assigned task is listed in #{taskInstanceListForType['approve']}, and can then be started. But how to start the task right away, so as soon as the task is assigned to oneself?

I could rewrite this to:

<s:button action="#{taskSelector.assignToCurrentActor}"
  |         taskInstance="#{task}" value="Assign"/>

  | public class TaskSelector {
  |     @In TaskInstance taskInstance;
  |     @In Actor actor;
  |     :
  |     public String assignToCurrentActor(){
  |         taskInstance.setActorId(actor.getId());
  |         // Or maybe one should use the following?
  |         // jbpmContext.getTaskMgmtSession().loadTaskInstance(taskId)
  |         //      .assign(actor.getId());	
  |         return taskInstance.getName();
  |     }
  |     :

This allows me to go to a task-specific page right away, but at that point the task has not been started yet. So this needs something more...

Thanks for any thoughts,
