我有一個奇怪的問題。我創建了一個簡單的複合組件與方法簽名：JSF複合組件只能在一頁中工作
<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>
這是行不通的，所以我已經在GlassFish中3.1.1更新鑽嘴魚科到2.1.4版本，但我不「知道爲什麼，它工作在一個XHTML文件，並沒有在作品其次...
在此有作品的權利：
<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>
根本就不在這方面的工作：
<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>
在第二頁我收到此錯誤：
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'.

另一個奇怪的事情是，在調試模式下它的方法進入，當方法完成拋出這個錯誤！下面是我想調用的方法（是pratically等同於其他的正確運行）：
public void buscarProdutos(AjaxBehaviorEvent evento) {
UIInput input = (UIInput) evento.getComponent();
String novoValor = (String) input.getValue();
carregarProdutos(novoValor);
}
我做錯了什麼事，我不能看？
感謝BalusC。我發現錯誤...該方法中的很多對象是這樣一句話： StringBuilder query = new StringBuilder（「SELECT p FROM Produto v WHERE p.descricao like：descricao」）; 我已將「v」更改爲「p」，並解決了問題。 :) – brevleq 2012-01-09 13:48:42
不客氣。 – BalusC 2012-01-09 13:49:39
