    completing human task - NoSuchFieldError: classLoader

    wishmaster7 Newbie

      Hi all,

       

      I have found something very strange when I complete a Human Task. Here is what I do:

       

      Map<String, Object> result = new HashMap<String, Object>();

      result.put("Result", action);

      taskService.completeWithResults(taskId, userId, result);

       

      and I have the following error:

       

      java.lang.NoSuchFieldError: classLoader

      So, I search in the code, and I find :

       

      MarshallerReaderContext context = null;

      context.classLoader = ContentMarshallerHelper.class.getClassLoader();

       

      BUT... (something I can't explain), MarshallerReaderContext has no classLoader. This throws the error above.

       

      Someone knows? Any help would be apreciated.
