问题 This question is about the Camunda BPM engine. I would like to implement an ExecutionListener that I can attach to any process events. This listener should send process state messages to a message queue. The process message should contain a state that would be "PENDING" for the process if the process is waiting in a UserTask somewhere. Now I wonder if there is an easy way to find out if the process is waiting (somewhere) in a UserTask inside the Delegation Code (by using provided

Own process instance can not be found inside a ServiceTask execution

由 落爺英雄遲暮 提交于 2019-12-11 01:54:36
问题 I have implemented a Camunda ServiceTask class (JavaDelegate) right after the start of my process. In this task I run a ProcessInstanceQuery for the own process instance (don't ask why). Surprisingly the query result is null - and I do not understand how this can happen. To reproduce the problem I created a very simple demo project at GitHub. This is the process and this is my HelloWorldTask execution code @Override public void execute(DelegateExecution execution) throws Exception { String

Camunda BPMN - Task listener vs Execution listeners

由 丶灬走出姿态 提交于 2019-12-06 01:35:41
问题 I've been using Camunda BPMN 2.0 for one of my workflow applications. In one of my service tasks, I created an execution listener at the start event and a task listener at the create event. I'm not sure whether it's proper to assign these simultaneously at the start event. If it's correct, which one of them will be getting executed first - Execution listener or Task Listener, at start or create event, respectively ? 回答1: Task listeners can only be used with user tasks, since they provide

How to specify which start event should be called from a BPMN callActivity

由 依然范特西╮ 提交于 2019-12-05 18:42:49
From http://www.omg.org/spec/BPMN/2.0.2/PDF on page 238: If the Process is used as a global Process (a callable Process that can be invoked from Call Activities of other Processes) and there are multiple None Start Events, then when flow is transferred from the parent Process to the global Process, only one of the global Process’s Start Events will be triggered. The targetRef attribute of a Sequence Flow incoming to the Call Activity object can be extended to identify the appropriate Start Event. How does one go about extending the targetRef attribute? Doesn't it have to be a valid IDREF?
