If the menu item for a usecase is enabled depends on the return value
of the method

   Usecase.checkPreconditions()

If your usecase extends, e.g., DocumentUsecase, you have to override

   doCheckPreconditions()

and add an error message if the workflow event cannot be invoked:

     protected void doCheckPreconditions() throws Exception {
         super.doCheckPreconditions();
         if (!WorkflowUtil.canInvoke(this.manager,
                 getSession(),
                 getLogger(),
                 getSourceDocument(),
                 getEvent())) {
             addErrorMessage("error-workflow-document",
                             new String[] { getEvent(),
                             getSourceDocument().getId() });
         }
     }
