    upgrade 3.2 -> 3.2.1 process definition problem

    Ricardo Marques Novice

      Hi guys, i recently had upgrade jbpm, but there is a problem on listing process definitions.

      I had this piece of code working:

      Command cmd = new GetProcessDefinitionCommand(true);
       DataModel model = null;
      
       try {
       List l = (List)getEngine().execute(cmd);
       model = new ListDataModel(l);
       }
       catch (Exception ex) {
       ex.printStackTrace();
       }
       finally{
       return model;
       }
      


      and after the update, there is no class GetProcessDefinitionCommand, only GetProcessDefinitionsCommand. So I changed, and I get a lot of these exceptions while listing:

      17:11:50,468 WARN [AbstractGetObjectBaseCommand] exception while retrieving process instance data for process definiton novo teste

      I suppose there's some problem here and something missing on the release notes.
