  | <task-node name="task4" end-tasks="true">
  | 
  | That will then end all open tasks when the node is left.

(1)what do you mean "task end"? I went through the source code and find out that the hibernate queries for findTaskInstance....() related methods only retrieve the "open" tasks. 

(2)What is the purpose of this "open" flag in  jbpm design? 

(3)Under what situation, will the  completion of a task instances trigger a signal on the token? In other words, who will response for the triggering of the token when a task instance is completed?

(4)I know token.signal() move the token to next node. But what is the function of "token.end()"? If a token and all of its children are ended, what does it mean?
