Hi,
I'm testing again and the problem is with decision activity. I have a process without decision activities and works fine. The same proces with a decision activity crash. I can't use the fork because I want two differents roads in the process, with a common finish.
I really think that the problem is with the joined finish, because all examples that work, are with differents finals, but don't work with joined finish.
I attach a picture that trivial process that don't work correctly.

This process crash in the submit of the "Train" or "Plane" FORM (JBPM console 2.0) you can see the error is in the first post. If I change the decision for a fork, the process work fine. But the problem obviously is that i want choose a task, don't the two.
I could duplicate the finish, but in my original process is more expensive.
Thanks again for your time and attention.
Mary.
