I’m not sure how to handle retries when it comes to handling failures for triggerable service tasks.
Let’s take a simple bpmn where it follows startEvent → serviceTask (async = true and triggerable = true) → endEvent
serviceTask (our custom JavaDelegate) makes rest calls to another service (let’s call serviceB) and goes to a wait state. Then serviceB will make callback to our flowable service with either SUCCESS/FAILURE callback. In case of SUCCESS callback, I can trigger and complete the task.
requirement: In case of failure callback, how do I ensure to retry the JavaDelegate.execute() method again? because the control of the flowable is in wait state of serviceTask now.
Our use case is to retry above requirement 3 times. After 3 retries move the execution to deadletter. When trying to bring back the execution from deadletter, again it should start from JavaDelegate.execute().
