与模板中的原子对话框重复出现ID错误 [英] Duplicate id error with primefaces dialog in template

问题描述

PF 3.5.10，Mojara 2.1.21，Omnifaces 1.5

PF 3.5.10, Mojara 2.1.21, Omnifaces 1.5

我有Facelet-Template with p：menu和p：include for dialog

I have Facelet-Template with p:menu and p:include for dialog

mytemplate.xhtml：

mytemplate.xhtml:

<h:form> ... <p:menubar> 
     <p:menuitem value="Start Dialog" oncomplete="mydialogwidget.show()"/>       
     <p:menuitem value="open another page" action="/app/mypage.xhtml?faces-redirect=true"/>
 </p:menubar>  ... </h:form>

<ui:insert name="content" />

<ui:include="/app/mydialog.xhtml" />

mydialog.xhtml：

mydialog.xhtml:

<ui:composition> 
  <p:dialog widgetVar="mydialogwidget" ...>
    <h:form>
    <p:datatable binding="#{mybean.table}">
       <p:column id="col_first"> ... </p:column> 
         ...
       <p:column id="col_last"> ... </p:colum>
    </p:datatable>
    </h:form>
  </p:dialog>
</ui:composition>

mypage.xhtml：

mypage.xhtml:

 <ui:composition template="/app/mytemplate.xhtml">
    <ui:define name="content">
    <h:form> ... </h:form>
    </ui:define>
 </ui:composition>

如果我启动mypage.xhtml表单，我将成为JSF1007错误（复制ids）组件树将写在我的控制台上简化的组件树输出：

If I start mypage.xhtml form menue, I become JSF1007 error (Duplicate ids) The component tree will be written to my console. The simplified component tree output:

+id: mydialog
  +id: mytable
    +id: col_first  <<=============
     ....
    +id: col_last 
    +id:col_first <<========

mydialog.xhtml 将仅包括一次。问题的答案具有Primefaces菜单重复Id错误的JSF 不帮助我
我该如何避免这个错误？这个错误从哪里来？

The mydialog.xhtml will be included only once. The answer to question JSF with Primefaces Menu duplicate Id error? doesn't help me. How can I aviod this error ? Where comes this error from ?

推荐答案

这个prolbem是datatable上的绑定属性。另请参见：绑定属性导致在视图中找到重复的组件ID

The prolbem was binding attribute on datatable. See also: Binding attribute causes duplicate component ID found in the view

SessionScoped组件在多个视图中使用。

SessionScoped component was used in multiple views.

我使用EL表绑定，然后问题消失了。

I've used EL-table binding and then the problem was disappeared.
