Buggy source:

Fixed version (ground truth):

      if (getStepReached(si) >= si.getSubmissionConfig().getNumberOfSteps()) {
        int lastStep=si.getSubmissionConfig().getNumberOfSteps() - 1;
        wi.setStageReached(lastStep);
        wi.setPageReached(AbstractProcessingStep.LAST_PAGE_REACHED);
        wi.update();
        context.commit();
        si.setSubmissionItem(wi);
      }
      setBeginningOfStep(request,true);
