Primefaces p：ajax和remoteCommand不更新咆哮消息

在以下示例中，我使用p：ajax修改數據表，然後使用remoteCommand更新表。這樣可行。不過，我還想在發生錯誤或成功時更新咆哮信息。這是行不通的。Primefaces p：ajax和remoteCommand不更新咆哮消息

我從例子中看到，如果一個按鈕調用一個動作，然後調用remoteCommand，growl消息更新。但是，這不會給我我需要從數據表中的ajax cellEdit。

如何從p：ajax命令更新growl消息。

您的'onCellEditRemote'遠程命令不會調用任何東西，因此最有可能不會更新任何內容。檢查網絡流量 – Kukeltje

其將工作P中添加partialsubmit：AJAX

錯誤的純空白（無逗號）被允許並以普通的jsf連唯一有效的值 – Kukeltje

抱歉，因爲不正確的答案 –

我工作圍繞這個問題從remoteCommand在modifyWordOnCellEdit創建和保存信息然後調用displayMessageAction來顯示它。不完全是我所希望的，但它的工作原理。

<p:remoteCommand name="onCellEditRemote" update="wordsId" action="#{gameBean.displayMessageAction}"/> 


    public void displayMessageAction() { 
     if (getMessage() != null) { 
      FacesContext.getCurrentInstance().addMessage("growl", getMessage()); 
      setMessage(null); 
     } 
    } 

    public void modifyWordOnCellEdit(CellEditEvent event) { 
    ... 
     FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR, exception.getMessage(), null); 
     setMessage(msg); 
    }
