Hi ,
I'm a newbie in the jbpm world,
I'm developing a sample process to evaluate Jbpm (4.4 ) but i encounter a lock in my process : i enter a fork ( parallel gateway ) , in this fork , one of the branches has an decision ( XOR Gate ) with 2 branches , and then , every branch goes back to a join.
The problem is that the XOR branches generate a lock on that join , what would be the appropriate solution ?
Here's my jpdl :
