[jboss-user] [JBoss jBPM] - possible nonthreadsafe access to session
Hi,
When trying to delete a process instance from the web application, I'm getting the
exception underneath.
It seems to be related to subprocesses. When the "super-process" includes a call
to a sub-process, it runs and ends normally but can't be deleted via the jbpm web
application any more. When running the process without the sub-process included, it can be
deleted.
Anyone any clue ?
Btw, I'm using jbpm 3.1.2 with the corresponding starter's kit.
