"StatefulKnowledgeSession signalEvent method" To view the discussion, visit: http://community.jboss.org/message/627040#627040 -------------------------------------------------------------- Hi, Can anyone help me to understand why the signalEvent method on the StatefulKnowledgeSession calls the ProcessInstancesWaitingForEvent query even when I provide the processInstanceId parameter? The ProcessInstancesWaitingForEvent seems to retrieve all workflow instances that are awaititing a particular event. I am seeing this behaviour in the context of this workflow: http://community.jboss.org/servlet/JiveServlet/showImage/2-627040-16993/data-v.0.0.2.jpg http://community.jboss.org/servlet/JiveServlet/downloadImage/2-627040-16993/450-205/data-v.0.0.2.jpg When I start the workflow with process variables that make it take the lower path the workflow begins and waits for the first signal. | | | ProcessInstance process = session.startProcess("com.bluecycle.zephyr.workflow.data-v0.0.2", processVariables); | At this point I am able to signal the first event and the ProcessInstancesWaitingForEvent is NOT called. The workflow quickly moves and waits for the second signal. | | | session.signalEvent("Signal1", null, process.getId()); | | At this point I can signal the second event which does succeed but this time it appeas to be calling the ProcessInstancesWaitingForEvent query to find all workflows waiting for the signal2 event.. | | | session.signalEvent("Signal2", null, process.getId()); | | The time that this takes is directly proportional to the number of workflow instances that I have waiting for the signal2 event. Can anyone help me to understand why ProcessInstancesWaitingForEvent is being called? It seems like this is unnessercary given that I am providing the processInsnanceId. Also I'm not sure why this happens when I signal event 2, but not when I signal event 1. The jbpm versions I have used are the ones bundled in the jbpm 5.10-Final installer download.
