=== Problem description =========================
I'm using JBPM 4.1 with a Seam 2.2.0/Richfaces 3.3.1 (no Pageflows). From a WebPage I try to set the assignee on a Task, it results in the Exception described above.
All other set* Functions on Task are working. TaskService.assignTask is working too!
Best Regards,
Joerg

I'm using the jobExecutor in all these examples on purpose as this is the only way I can show what is happening. Executing job one by one isn't async obviously and thus signalling the jobs doesn't reproduce this issue.
