＆＃34;找不到带有标识符的组件＆＃39;问题

Question

我遇到了JSF页面的问题。 我正在使用primefaces 3.4

我想更新一个小组。

错误消息

 javax.faces.FacesException: Cannot find component with identifier ":mainform:panelValeurs" referenced from "menuform:mainform:table_ligne:0:j_idt93".

问题在于此按钮的“更新”

<p:commandButton
    title="#{bundle.modifier}" icon="ui-icon-pencil" 
    action="#{listeChoixBean.editListeValeurLigne()}" 
    process="@this" update=":mainform:panelValeurs">
    <f:setPropertyActionListener target="#{listeChoixBean.selectedListeValeurLigne}" value="#{ligne}" />
</p:commandButton>

'更新'值以“：”开头，所以我不明白为什么它不起作用。 信息：'menuform'（错误消息）在模板中

非常感谢人们帮助我！
