I have a process, contains approve and reject. if reject,the process should return to usertask1.

if I write the process definition file using hand(without the eclipse plugin),it will throw a exception:

ProcessLoadError: unable to parse xml : Exception class java.lang.IllegalArgumentException : This type of node cannot have more than one incoming connection!

imo, what I said should be a common request/case.

so why jbpm5.3 usertask  support only one incoming connection?

Hope someone can answer my question,thx a lot.
