How do I listen for custom event and only move forward if certain conditions are met

bhattsu

I have a simple process with a a receive task. ( I am ok with any other task type).

I want the receive task to move forward only if an event is received with event type CUSTOM and message="Move Forward"

How do I create a listener for this scenario and how do I throw event using Java API along with message variable.

Have you tried in the way that it is described in the documentation? -> Activiti User Guide ?

Hi, Sude Bhat‌

You can use the event listeners to and set a custom variable value i.e. message="Move Forward" as and check the forward if value is same then do what you want,
Refer this documentation , How to create Activiti Event Listener with Spring Boot Example - JavaSampleApproach

Thanks,

Hi Mauricio -

I have been scratching my head on this. I have read all of these. Nowhere I see an event ExecutionListener that says "oh the message I got is not the one I care about so I will not the wait task to move forward". How can an ExecutionListener prevent a task from moving forward depending what message variable it receives?

Hi Kalpesh -

But in this case, the right approach would be to use ExecutionListner right? I read ActivitiEventListener can be only defined at the process level.

I am at "Receive Task" and I want Receive Task to only move forward if I get message="Move Forward". So I have to put the logic in Receive Task right?

Thank you
