Hi,
one good news and one bad news.
The good news is: Now I can start my process. I added a simple form, contains only a submit button , and reload everthing. Now it starts.
bad news:
I run into an NullPoineterException:

Thin NPE only occurs if I use a asynchr. behavior. Asynchr. means manager.completeWorkItem is not called by WorkItemHandler, another Thread calls manager.completeWorkItem .
Some ideas?
Many thanks,
