i can access all these variables in my main process - any event,lisenter,java module hooks.
but these same variables are not able to my sub-process custom module.
i tried to get parent.getProcessInstance.getVariable also.. parent is comming as null..ublic class IngestBookActivity implements ExternalActivityBehaviour { public void signal(ActivityExecution execution, String signalName, Map<String, ?> parameters) throws Exception { System.out.println( " Parameters "+parameters); String prodCd = (String)execution.getVariable("prod-cd"); String prodType = (String)execution.getVariable("product-type"); /** both prod-cd, prod-type comming as null */ IngestionControl pojo = new IngestionControl(); pojo.setProdCd(prodCd); pojo.setProdType(prodType); String executionPath = "trSuccess"; try { doIngestion(pojo); System.out.println(" IngestBook Activity --- Book Ingested Successfully "); } catch (Exception e) { e.printStackTrace(); executionPath = "trFailure"; } execution.take( executionPath); }

sebastian.s Dec 13, 2009 10:41 AM (in response to emailkuppai)Might be related to your problem:
https://jira.jboss.org/jira/browse/JBPM-2485
Also refer to the post mentioned in the JIRA (regarding a workaround):
http://community.jboss.org/thread/118912?tstart=0
Ronald, did I get you right when saying you proposed passing the variables into the sub-process by using the parameter-attribute in the process definition of the main process as it is described in the documentation?

Yes, since that is what is the way to do it at the moment.
