问题
I have a requirement where I need to execute 4 jobs parallel and when same items job is done in all 4 processors parallely then trigger the next processor for this I have used wait-notify
Flow is like 4 parallel jobs -> notify (release signal identifier = ${itemid}, signal counter name = ${processorname}) -> wait (release signal identifier = ${itemid}, target signal count = 4) and wait relationship is connected to the same wait processor-> next processor
This works for first time but I have noticed that wait queue is not cleared even after the target signal count condition is met and i guess that is the problem it is not working for subsequent flows.
It should clear the waiting queue once the criteria is met right?
