EnvironmentImpl environment = ((ProcessEngineImpl) processEngine).openEnvironment();     try{     ProcessDefinitionImpl pdf = execution.getProcessDefinition();     ActivityImpl activity = pdf.getActivity(taskName);          if ("custom".equals(activity.getType())) {            Object model= activity.getProperty("model");            System.out.println("model = "+ model);           }     }catch(Exception ex){     }finally{       environment.close();     } ============== sadly, I got "null" with this manner. Could you please give me some clue? I am a newer. Thanks very mcuh. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/624702#624702] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
