JSF Primefaces Commandbutton沒有更新AJAX

我想在選中表
「dataTableSupUserRoles」的一個元素後更新Button「buttonEditRole」。當選擇了一個元素
時，該按鈕應該啓用。行選擇後的偵聽器方法被調用。
在這個方法中，我將「disableNewSupUserRoleButton」設置爲true。這也適用，但按鈕不啓用。
這裏是我的XHTML：JSF Primefaces Commandbutton沒有更新AJAX

與聽者方法：

public void onSupplierUserRoleRowSelect(SelectEvent e){ 

    this.disableSupUserRoleButtons=false; 
}

只是爲了測試嘗試刪除標記直接或值更改爲false，如果不行試試改變你的更新代碼ajav事件@form –

感謝您的答覆！我試過了你的兩個提示，但它仍然不起作用。 – hiaslosch17

@ hiaslosch17支持bean的範圍是什麼？總是建議使用'@ ViewScoped'來獲得使用ajax操作的最佳結果 – kolossus

可以更新整個窗體，而不是命令按鈕。

試試這個：

update = "@form"
