    @CreateProcess and SeamTest - help w. NullPointerException

    Bradley Smith Master

      I am trying to test the creation of a new jBPM ProcessInstance. My SFSB's method is:

       @CreateProcess(definition = "RequestNewAccess")
       public String sendRequest() {
       log.info("sendRequest() : accessRequest -> " + this.accessRequest);
       log.info("sendRequest() : Actor -> "+this.actor);
       return "success";
       }
      


      from my SeamTest, I have setup an authenticated user, mapped that onto the jBPM Actor (using answer to my last question - thanks), etc... Anyway, I invoke the sendRequest() method in the test like such:

       ....
       @Override
       protected void invokeApplication() {
      
       ....
      
       AccessRequestManager accessReqMgr = (AccessRequestManager)getInstance("accessRequestManager");
       assert accessReqMgr != null;
       accessReqMgr.chooseApplicationsForAdd();
       assert "success".equals(accessReqMgr.sendRequest());
      
       }
       ....
      


      and I get the following NullPointerException:

       ... 68 more
      


      and, of course, the ProcessInstance is not created. Line 94 in BusinessProcessInterceptor.java (from Seam) is:

      BusinessProcess.instance().createProcess( tag.definition() );
      


      one of the 4 references here is null.... maybe there is something missing from my test environment? Any help appreciate.

      Thanks,
