Hi all,
I had a processdefinition.xml used to work fine. Today, when I tried to open it in jBPM
GPD, I got an exception and it didn't open anymore. Then, I created a new process
definition and, smartly, copied the xml code from the first process definition I had to
this new one. As a result, it didn't open either.
Guess what must be happening? The error raised is:
