Your usertasks are not assigned to anyone, hence why you can't see anything in your task list.

But you should see something when you log into Probe and look at the ACT_RU_EXECUTION table.

Thanks for the answer.
Yes, there I can see that the process ist set running.
How can I assign a process to anyone so that it's also possible to see (and handle) it in the Activiti explorer at the Tasks - section?
