Question

I need to be able to “wake up” a sequential workflow service – and this concept worked in a State Machine previously so I’m not understanding why it doesn’t work in the Sequence. Below is a picture of the workflow.

This workflow is used for orchestration of other workflow services. It literally needs to run forever – but we need the ability to shut it down softly. Previously I had this same type of thing implemented in a State Machine, the Delay was the trigger for one transition and the Receive was the trigger for another. As long as the first mentioned transition wasn’t running I was able to get the Receive to take the message and transition to the final state. Here what I want to do, as you can see, is just set the boolean value to False indicating that the While loop should exit and thus the workflow would terminate.

Please help me understand why this isn’t working.

Thanks all!

You should get some tracking data – this will help you to understand what is going on. See Troubleshooting Workflow Services with diagnostic logging
