Re: [shark] Process must have some requester


from your description, I assume that you use asynchronous subflow.
Also, you are probably deleting the "Main" process from DB before 
asynchronous subflow finishes, and this is why you get this
If above assumptions are correct, it is a bug in Shark - it shouldn't throw 
such exception in the case of asynchronous subflows.
The workaround solution for you would be to not delete "Main" process from DB 
until asynchronous subflow processes that are started
from this process does not finish.

Thanks for reporting,

Subflows. We tried also to abort the Processes via the 
ExecutionAdministration, but in any case we got a BaseException "Process must
have some requester". Only solution is to recreate the DB, so that we can 
Reload the XPDL Definition. And we think this is not the
best Solution.
