java - JSF Composite 组件仅在一页中运行

Question

我遇到了一个奇怪的问题。我创建了一个带有方法签名的简单复合组件:

<c:interface>
    <c:attribute name="valorBusca" default="" required="true" type="java.lang.String"/>
    <c:attribute name="listenerBusca" required="true" method-signature="void buscarAlgo(javax.faces.event.AjaxBehaviorEvent)"/>
    <c:facet name="filtrosAdicionais"/>
    <c:facet name="tabela"/>
    <c:facet name="informacoes"/>
</c:interface>

<c:implementation>
<h:outputStylesheet library="css" name="clearfix.css" target="head"/>
<h:outputStylesheet library="css" name="camposFormulario.css" target="head"/>
<h:outputStylesheet library="css" name="listagem.css" target="head"/>
<h:panelGroup layout="block" styleClass="hrgi-div-form tamanho-aba-cadastro clearfix">
    <p:fieldset legend="Filtro" styleClass="clearfix" style="width: 94.5%">
        <h:panelGroup layout="block" styleClass="clearfix">
            <h:outputLabel value="Buscar:"
                           title="Insira a informação a ser buscada."
                           styleClass="hrgi-label-form hrgi-listagem-label" style="padding-right: 8px;"/>
            <p:inputText value="#{cc.attrs.valorBusca}"
                         autocomplete="off" immediate="true" style="width:90%"
                         title="Insira a informação a ser buscada.">
                <f:ajax event="keyup" render="tabelaListagem" execute="@this"
                        immediate="true" listener="#{cc.attrs.listenerBusca}"/>
            </p:inputText>
        </h:panelGroup>
        <c:renderFacet name="filtrosAdicionais" required="false"/>
    </p:fieldset>
    <h:panelGroup id="tabelaListagem" layout="block" class="clearfix"
                  style="width:99%; margin: 1em auto 0 auto;">
        <c:renderFacet name="tabela" required="true"/>
    </h:panelGroup>
    <h:panelGroup id="painelInformacoes" layout="block" styleClass="clearfix">
        <p:fieldset legend="Informações" style="width: 94.5%">
            <c:renderFacet name="informacoes" required="true"/>
        </p:fieldset>
    </h:panelGroup>
</h:panelGroup>

它不起作用，所以我在 glassfish 3.1.1 中将 mojarra 更新到版本 2.1.4，但我不知道为什么，它在一个 xhtml 文件中工作，但在另一个 xhtml 文件中不起作用...

在这里它工作正常:

<ui:composition template="../templates/popup.xhtml">
<ui:param name="titulo"
          value="#{vendaMsg['popup.adicionar_produto.titulo']}"/>
<ui:param name="popup" value="#{modeloPopupCarregarProduto}"/>
<ui:param name="controladorPopup"
          value="#{controladorPopupCarregarProduto}"/>
<ui:define name="conteudo">
    <h:panelGroup layout="block" styleClass="hrgi-div-form clearfix">
        <hrgi:listagem listenerBusca="#{controladorPopupCarregarProduto.buscarProdutos}"
                       valorBusca="#{modeloPopupCarregarProduto.valorBusca}">

            .............................

        </hrgi:listagem>
    </h:panelGroup>
</ui:define>
</ui:composition>

并且根本不起作用:

<ui:composition template="../templates/popup.xhtml">
<ui:param name="titulo" value="#{cadastroMsg['popup.cadastro.listagem_produto.titulo']}"/>
<ui:param name="popup" value="#{modeloPopupListagemProduto}"/>
<ui:param name="controladorPopup" value="#{controladorPopupListagemProduto}"/>
<ui:define name="conteudo">
    <h:panelGroup layout="block" styleClass="hrgi-div-form clearfix">
        <hrgi:listagem listenerBusca="#{controladorPopupListagemProduto.buscarProdutos}"
                       valorBusca="#{modeloPopupListagemProduto.valorBusca}">

                       .................................

        </hrgi:listagem>
    </h:panelGroup>
</ui:define>
</ui:composition>

在第二页中我收到此错误:

javax.el.PropertyNotFoundException: /resources/components/popups/modulo_cadastro/popupListagemProduto.xhtml @18,82 listenerBusca="#{controladorPopupListagemProduto.buscarProdutos}": The class 'com.hrgi.ui.controladores.popups.ControladorPopupListagemProduto' does not have the property 'buscarProdutos'.

另一个奇怪的事情是，在 Debug模式下它进入方法，当方法完成时抛出此错误!这是我尝试调用的方法(实际上与正确运行的其他方法相同):

public void buscarProdutos(AjaxBehaviorEvent evento) {
    UIInput input = (UIInput) evento.getComponent();
    String novoValor = (String) input.getValue();
    carregarProdutos(novoValor);
}

我做错了一些我看不到的事情？

Answer 1

buscarProdutos() 方法实际上自己抛出了一个异常，但是由于 currently open bug (issue 1806)与调用复合组件中的操作相关，它会被吞没并作为 PropertyNotFoundException 重新抛出。

您可以在调试器中找到真正的异常和/或通过将方法主体放入try-catch并记录它。我敢打赌，是 carregarProdutos() 方法引发了异常。
