自定义或更改工作流对话框发出的有关Alfresco错误的默认消息框

Question

现在,出现一个消息框,其中包含失败的类名:

是否可以覆盖Alfresco中的默认行为？我们可以使用表单服务来呈现不同的消息吗？

除了zladuric答案,

你可以使用failureCallback方法来显示你想要的消息.但是很难为新的工作流形式搜索failureCallback方法,因为工作流形式如"开始工作流","任务编辑","任务详细信息"用于表单引擎.

例如,在" 开始工作流 "表单中,您可以添加我们自己的表单,successCallBack并在start-workflow.js中failureCallBack编写onBeforeFormRuntimeInit事件处理程序.

 onBeforeFormRuntimeInit: function StartWorkflow_onBeforeFormRuntimeInit(layer, args)
          {
            var startWorkflowForm = Dom.get(this.generateId + "-form");
            Event.addListener(startWorkflowForm, "submit", this._submitInvoked, this);

            args[1].runtime.setAJAXSubmit(true,
             {
                successCallback:
                {
                   fn: this.onFormSubmitSuccess,
                   scope: this
                },
                failureCallback:
                {
                   fn: this.onFormSubmitFailure,
                   scope: this
                }
             });
          }

 onFormSubmitSuccess: function StartWorkflow_onFormSubmitSuccess(response)
      {
        this.navigateForward(true);
    // Show your success message or do something.
      }
onFormSubmitFailure: function StartWorkflow_onFormSubmitFailure(response)
      {
        var msgTitle = this.msg(this.options.failureMessageKey);
        var msgBody = this.msg(this.options.failureMessageKey);

        // example of showing processing response message
        // you can write your own logic
        if (response.json && response.json.message) 
        {
            if(response.json.message.indexOf("ConcurrencyFailureException") != -1) 
            {
                msgTitle = this.msg("message.concurrencyFailure");
                msgBody = this.msg("message.startedAgain");
            }
            else
                msgBody = response.json.message;
        }
        Alfresco.util.PopupManager.displayPrompt(
                {
                    title: msgTitle,
                    text: msgBody
                });
      }

因为Alfresco.component.StartWorkflow(在start-workflow.js中)扩展Alfresco.component.ShareFormManager(在alfresco.js中).您可以在start-workflow.js中覆盖onBeforeFormRuntimeInit事件.我希望你的帮助.
