  | public void testDoDirty() {

  | 				.getProcesssInformationService();
  | 		System.out.println("TEST");
  | 		// ProcessInstance processInstance =
  | 		// pisrv.startProcess("wf_ingest_book");
  | 		String pid = "wf_ingest_book";
  | 		String cid = System.currentTimeMillis() + "";
  | 		Map<String,Object>  variables = new HashMap<String,Object>();
  | 		variables.put("product-type","book");
  | 		variables.put("ingest-type","meta-only");

  | 		variables.put("c-id", "");//Some CID Number 
  | 		ProcessInstance processInstance = pisrv.startProcess(pid,variables, cid);

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..

  | 	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);
  | 	}
