          please use code tags to post a process (do a preview to see the result)

            and post the code you end the task in and post version numbers and preferably post a unit test (see the testcases of jBPM for examples)

                Since you did not post a stacktrace or the code of the timer as requested, it is still almost impossible to help, but I'll give it a try.

                You probably end the task in the timer, you should not do that. You should define a transition that has be taken and define the open tasks to end if the tasknode is left.

                    Ronald van Kuijk Master

                    Great,

                    Several things. You post you end a task in a timer. Looking at the code you don't (anymore) So that is impossible to check. Second, the error post occurs while while retrieving a task list, not when ending a task. Could it be you have multiple threads or something? Besides that, I see you get the exception from the main thread? Are there two jbpm instances running on the same database? Or is your scheduler an external process? The error now is in a completely

                    Again, post a unit test with a process definition that is stripped of all unneeded things.

                    One thing I see that something goes wrong in retrieving a tasklist.

                    Do you do that in the assignment handler to achieve some kind of workloadbalancing?
