【问题描述】:
我创建了一个 ui:component 来像弹出窗口一样使用,所以我可以使用这个模板的标准创建很多弹出窗口。 该组件只是一个带有两个按钮(取消和提交)和一个可以被覆盖的内容的弹出窗口,就像您在此处看到的那样:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

xmlns:p="http://primefaces.prime.com.tr/ui">
<ui:component>
<p:dialog widgetVar="#{idPopup}" id="#{idPopup}" modal="#{popup.modal}"
draggable="#{popup.modal}"
rendered="#{popup.visivel}" visible="#{popup.visivel}"
closeOnEscape="false" closable="false" header="#{titulo}"
resizable="false" styleClass="autoWidthDialog" showEffect="fade"
hideEffect="fade">
<h:panelGroup style="width:100%">
<p:focus />
<ui:insert name="conteudo">Nenhum conteúdo definido!</ui:insert>
<h:panelGrid id="#{idPopup}PainelMensagens" style="width:100%">
<p:messages />
</h:panelGrid>
<ui:insert name="barraDeBotoes">
<h:panelGroup layout="block" style="width:100%">
<p:commandButton value="CANCELAR" immediate="true" update="@form"
style="float:right" action="#{controladorPopup.fechar}"
onclick="#{idPopup}.hide();" />
<p:commandButton value="OK" style="float:right"
update="@form formAlerta"
action="#{controladorPopup.submit}"
process="@form" />
</h:panelGroup>
</ui:insert>
</h:panelGroup>
</p:dialog>
</ui:component>
</html>
当我尝试在未填写必填字段的情况下提交表单时会出现问题。正确的行为是再次显示带有消息的弹出窗口,但对话框呈现两次,一次带有消息,另一次不带消息。 您可以在此处查看此行为:
这是此模板的一种用途:
<ui:composition template="../templates/popupSubmit.xhtml">
<ui:param name="titulo" value="Buscar pessoa" />
<ui:param name="popup" value="#{modeloPopupBuscaPessoa}" />
<ui:param name="controladorPopup"
value="#{controladorPopupBuscaPessoa}" />
<ui:define name="conteudo">
<h:panelGroup>
<h:panelGrid columns="2">
<h:outputLabel value="Tipo de cadastro:" style="float:none" />
<h:selectOneMenu value="#{controladorSugestaoPessoa.tipoCadastro}"
immediate="true">
<f:selectItems value="#{carregadorTipoCadastro.itens}" />
<f:ajax event="change" immediate="true" />
</h:selectOneMenu>
</h:panelGrid>
<h:outputText value="Buscar por:" />
<h:selectOneRadio value="#{controladorSugestaoPessoa.tipoBusca}"
immediate="true">
<f:selectItems value="#{carregadorTipoBuscaPessoa.itens}" />
<f:ajax event="change" immediate="true" />
</h:selectOneRadio>
<p:autoComplete value="#{modeloPopupBuscaPessoa.itemSelecionado}"
forceSelection="true" maxResults="10" queryDelay="500"
completeMethod="#{controladorSugestaoPessoa.atualizarSugestoes}"
var="pessoa" itemLabel="#{pessoa.label}" itemValue="#{pessoa}"
converter="#{conversorSelectItem}" />
</h:panelGroup>
</ui:define>
</ui:composition>
还有这些用处:
<h:form id="cadastroPessoa">
<ui:include
src="resources/components/popups/modulo_cadastro/popupNovoCadastroPessoa.xhtml">
<ui:param name="idPopup" value="popupNovoCadastroPessoa" />
</ui:include>
<ui:include
src="resources/components/popups/modulo_cadastro/popupCadastroPessoa.xhtml">
<ui:param name="idPopup" value="popupEdicaoCadastroPessoa" />
</ui:include>
<ui:include
src="resources/components/popups/modulo_cadastro/popupBuscaPessoa.xhtml">
<ui:param name="idPopup" value="popupBuscaCadastroPessoa" />
</ui:include>
</h:form>
<h:form id="cadastroProduto">
<ui:include
src="resources/components/popups/modulo_cadastro/popupCadastroProduto.xhtml">
<ui:param name="idPopup" value="popupNovoCadastroProduto" />
</ui:include>
</h:form>
谁能告诉我为什么会这样??
【问题讨论】:
-
能否把与该片段相关的模板和模板客户端中的代码也贴出来?
-
不确定是否是整个问题的原因,但将对话框设计为包含文件有点奇怪。标记文件或复合组件是更明智的选择。此外,对话框还应该有自己的
<h:form>,而不是放在任何<h:form>中。提交对话框中的字段时,您不希望以相同的形式提交/处理对话框外页面中的所有其他字段。
