Richfaces 4，a4j：命令渲染另一個h：表格

Question

a4j:commandLinkdataTable如何渲染UI Component的另一個h:form？ 在tableForm，當我點擊編輯a4j:commandLink的部門datatable,ajax無法渲染部門的entryForm。 我也嘗試使用ajax:region它不起作用，並沒有顯示任何錯誤。我不知道爲什麼。

Answer 1

嘗試使用屬性render =「@ all」。請使用螢火蟲驗證呈現的表單id是否僅爲「entryForm」，或者是否已添加一些JSF前綴。這可能是因爲render =「entryForm」不起作用。

Answer 2

你應該傳遞你想用ajax渲染的控件的完整id。一個基本的例子：

<h:form id="form1"> 
    <h:inputText id="txtSomeName" value="#{bean.name}" /> 
    <a4j:commandButton value="Click me" render=":form2:txtName" /> 
</h:form> 
<h:form id="form2"> 
    <h:inputText id="txtName" value="#{bean.name}" /> 
</h:form>
