java.lang.IllegalArgumentException：找不到屬性類的Setter

Question

我想用行編輯實現一個表。

我在櫥窗中發現this exemple，但我得到這個錯誤埃夫裏的時間：

• javax.servlet.ServletException：二傳手找不到財產類
• java.lang.IllegalArgumentException異常：二傳手未找到物業 類

我XHTML

這可能與你的壞屬性：

<a4j:commandLink class="lien_detail" /> 

沒有爲組件a4j:commandLink你應該使用styleClass，而不是無屬性class。
