Doubled tasks in an execution

[slavomir]

Hi, I've got an Activiti code (Activiti 5.19 run with Camel on Servicemix) running in production and face some peculiar problem: sometimes (like 8 times in last few Months) I've got cases of doubled tasks in an execution.

Tasks either cannot be completed (resuling "UserTask should not be signalled before complete" exception) or deleted because are part of the running execution.

I cannot figure out what could cause such an effect and to get rid of the redundant tasks in order to finish the damaged processes.

Is there possible to just delete the later records (with the highest task id) in the act_ru_task?

Anybody could help?

I've figured out the root-cause are doubled tasks for the execution. The question is now: is that possible for Activiti to let create accidently a new task while the first one wasn’t closed?

And the second question is what method should be used to delete the redundant task?

Hi,

I have the same problem, have you figured out the solution?

Is there a way to solve this problem?

[slavomir]

I'm afraid not. I've created a workaround and started migration out from Activiti. Fortunately in my case so complex task management was simply not required.

Im using 5.22.0 version, im thinking also about a workaround which will retrieve only one execution. 

May be there is another way to avoid this
