Hi guys,
You are right that my process looks weird. It is because I took a part of a bigger process, and made a test case out of it. Join3 that is followed by Fork2 was inserted because I suspected every fork must be followed by a join, and not another fork. Sadly it didn't help much. The simple test case can be rewritten without nested forks, but our real process cannot. So I will check out the 4.4 snapshot and see if that solves my problem. Thanks for your help!
Regards, Johan
