Передать текст в контейнер PortalMessagePublisher

Что-то вроде такого:

define("SupportPortalCasePage", [], function() {
 return {
  entitySchemaName: "Case",
  details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
  diff: /**SCHEMA_DIFF*/[]/**SCHEMA_DIFF*/,
  rules: {},
  modules: {
   ActionsDashboardModule: {
    "config": {
     "isSchemaConfigInitialized": true,

        "orderColumnName": "StageNumber"
       },
       "DashboardConfig": {

         }
        }
       }
      }
     }
    }
   }
  },
  methods: {

    this.callParent(arguments);
    this.setPortalMessageHint();
   },

   }
  },
