[jboss-user] [JBoss jBPM] - Question about tasks and task node

[SuperBee]

I define a task node, which contains multiple tasks, in the process definition. My question is: The tasks contained in the task node are not performed sequently, some of the tasks are performed iteratively for several times, how can I define the task node and the tasks? 
For example, the task node "restaurant" has 3 tasks: "call menu", "order", and "finish dinner". The tasks "call menu" and "order" will perform iteratively until "finish dinner" command is executed, then "finish dinner" task is performed, and the task node is signaled. We can imagine that a guest will call menu to add more dishes before he finishes eating.
