几天前我将 mojarra 更改为 myfaces 来解决这个问题,现在我在渲染我的复合组件时遇到了一个奇怪的问题,当我第二次打开一个弹出窗口时它们根本没有渲染(弹出窗口也是一个复合组件) .
第一次,正如您在 fieldset 中看到的,一切正常:
然后我点击“CANCELAR”(取消)按钮,第二次,除了对话框,我的复合组件都没有被渲染:
当我查看日志时,我发现了这些消息:

如您所见,问题是 myfaces 在复合组件中找不到构面...唯一使用构面的复合组件是 hrgi:popup:
<c:interface>
<c:attribute name="titulo" default="sem titulo" required="false"/>
<c:attribute name="renderizar" default="false" required="false"/>
<c:attribute name="modal" default="true" required="false"/>
<c:attribute name="bordaConteudo" default="true" required="false"/>
<c:facet name="cabecalho" required="false"/>
<c:facet name="conteudo" required="true"/>
<c:facet name="botoes" required="true"/>
</c:interface>
<c:implementation>
<h:outputStylesheet library="css" name="hrgiPopup.css" target="head"/>
<h:outputStylesheet library="css" name="clearfix.css" target="head"/>
<h:outputScript library="js" name="hrgiPopup.js" target="head"/>
<h:panelGroup layout="block" rendered="#{cc.attrs.renderizar}"
class="hrgi-dialog-panel clearfix">
<h:panelGroup layout="block" class="hrgi-dialog-overlay clearfix" rendered="#{cc.attrs.modal}"></h:panelGroup>
<h:panelGroup id="popup" layout="block" class="hrgi-dialog-box clearfix">
<h:panelGroup layout="block" class="hrgi-dialog-title clearfix">
<h:outputText style="float:left" value="#{cc.attrs.titulo}"/>
</h:panelGroup>
<h:panelGroup layout="block" class="hrgi-dialog-content clearfix">
<c:renderFacet name="cabecalho" required="false"/>
<h:panelGroup layout="block" class="hrgi-dialog-background clearfix"
rendered="#{cc.attrs.bordaConteudo}">
<c:renderFacet name="conteudo" required="true"/>
</h:panelGroup>
<h:panelGroup layout="block" class="clearfix" rendered="#{not cc.attrs.bordaConteudo}">
<c:renderFacet name="conteudo" required="true"/>
</h:panelGroup>
<c:renderFacet name="botoes" required="true"/>
<script type="text/javascript">
cercarEventoTab("#{cc.clientId}:popup");
</script>
</h:panelGroup>
</h:panelGroup>
</h:panelGroup>
</c:implementation>
这是 MyFaces 的错误吗?Mojarra 没有显示出任何这样的问题!
更新
问题只是在用户单击“取消”按钮时发生......该操作调用此代码以清除字段并关闭对话框:
public void cancelar(ActionEvent evento){
fechar();
UIComponent componente=evento.getComponent().getParent().getParent().getParent();
componente.getFacet("conteudo").getChildren().clear();
}
此代码改编自您可以在此处看到的方法。在这种情况下,仅重新创建 facet conteudo 内的组件。工作正常,除了我的复合组件。
