"Problem with multiple process instances and HumanTasks" To view the discussion, visit: http://community.jboss.org/message/641019#641019 -------------------------------------------------------------- Hi I have a process involving 3 HumanTask nodes and 2 CustomService nodes. All works fine if I just run one instance of this process, when I try to setup 2 instances, strage things starts to happend. Looks like the processes influence with each other. My question is how to setup session and knowlegde base to support mulitple instances of my process. I use this strategy to setup my session and prosesses - is this correct? 1) When application starts up we read the knowlegdebase (only done once) 2) After 1 is completed we setup the session (global session reused) session = kbase.newStatefulKnowledgeSession() - global and reused trough application 3) When we need to start a new process, a new instance is created with the global session Have tried different solutions, right now this is what's done when starting up a new process instance: //Register two custom work nodes session.getWorkItemManager().registerWorkItemHandler("START", new ApplicationWorkManager()); session.getWorkItemManager().registerWorkItemHandler("APPROVED", new ApplicationWorkManager()); //Register Human Task handler CommandBasedWSHumanTaskHandler handler = new CommandBasedWSHumanTaskHandler(appsession); session.getWorkItemManager().registerWorkItemHandler("Human Task", handler); WorkflowProcessInstance process = (WorkflowProcessInstance) appsession.startProcess("no.my.Process",parameters); With just one active process things are fine, starting a second process - strage things starts to happend. E.g process number 2 skips the first Human Task which is active in process 1. Is the setup I use correct? Shall I just register WorkItemHandler once? How can i reuse my session for difference process instances? Hope someone can help out here.. I think (and hope) JBPM is able to handle multiple instances of a process. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/641019#641019] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
