Hi philsegal, kukeltje and others,
I think I misunderstand this topic.
Could you, please, read my process definition and test case ? Sorry for not using assert()
correctly, I currently can't remove the println() from my code. The questions I ask
are in the test case comments.
Thanks in advance for your help. I was not able to find any JIRA information. This forum
thread seems to be related to my problem.
