intermediateCatchEvent is not working in flowable

rasmikanta · November 28, 2017, 11:35am

IntermediateCatchEvent is not working in flowable after specifying a particular time.
Below is the flowable bpmn code snippet

After this the flow is not going forward. But without this, the flow is working.

Hi,

I’m confused. What is not working? If you use a timer catch event, the process instance will wait until the timer needs to be executed. How are you running the Flowable Engine? Can you share your configuration?

Best regards,

Tijs

While running the bpmn, it is stopped at the timer(intermediatecachevent) and not going further even if the time that I have given to run expired. If I am removing timer, it is running smoothly.

I am having the same issue. Execution is not proceeding to next step if I put intermediate timer event with some delay. If I remove this it is working fine. Please help. Below id my config
