--------------------------------------------------------------
I have the same problem here (I had the same exception as you Franck cdsosi). I am able to create new process instances and they are shown in the list.
But when I go to the Task List, nothing shows up, even if I refresh.

I have stopped the debugger, tried to terminate processes and created new ones but they just don't appear in krisv's task list.

Here is a piece of the server.log
