我正在开发一个JSF2.1项目，prettyfaces，hibernate 4，primefaces 我在这里遇到问题...我有一个p：commandbutton调用ajax请求，其中条件检查，财务年度是否打开
<p:commandButton id="isFinancialYearSubmitId" value="submit" update="isFinancialYearBooleanPanelGridId scenarioTabViewId:budgetAnalysisDataTableId" action="#{budgetAnalysisAction.isFinancialYearOpened}" oncomplete="isFinancialYearOpenedOnComplete();"/>
有3个值...如果财务年度开启则如果财务年度结束则为'1'然后如果无效则为'0'然后'-1' 如果财务年度关闭或无效，则图像会加载一些文本，但问题在这里 如果财政年度开放，那么我想生成一个p：dataTable
<h:panelGrid columns="2" id="isFinancialYearBooleanPanelGridId" styleClass="panelGridCenter" >
<h:column>
<ui:fragment rendered="#{budgetAnalysisAction.budgetFinancialYearBean.financialYearForProposalsBean == '-1'}">
<ui:fragment rendered="#{budgetAnalysisAction.util.errorCode == '-1'}" >
<h:outputText value="<div class='n_error'><p>Error . #{budgetAnalysisAction.util.errorMessage}</p></div>" escape="false"/>
</ui:fragment>
</ui:fragment>
<ui:fragment rendered="#{budgetAnalysisAction.budgetFinancialYearBean.financialYearForProposalsBean == '0'}">
<ui:fragment rendered="#{budgetAnalysisAction.util.errorCode == '-1'}" >
<h:outputText value="<div class='n_error'><p>Error . #{budgetAnalysisAction.util.errorMessage}</p></div>" escape="false"/>
</ui:fragment>
</ui:fragment>
</h:column>
<h:column>
<ui:fragment rendered="#{budgetAnalysisAction.budgetFinancialYearBean.financialYearForProposalsBean == '1'}">
<p:tabView id="scenarioTabViewId" style="width:850px" >
<p:tab title="Scenario One" id="scen">
<p:dataTable id="budgetAnalysisDataTableId" editable="true" scrollable="true" scrollWidth="800" resizableColumns="true" value="#{budgetAnalysisAction.budgetScenarioHescoProposalBean.budgetScenarioHescoProposalListBean}" var="budgetScenarioHescoProposalList">
… HERE ARE SOME COLUMNS
</p:dataTable>
</p:tab>
</p:tabView>
</ui:fragment>
</h:column>
</h:panelGrid>
当我提交命令按钮时，update =“isFinancialYearBooleanPanelGridId scenarioTabViewId：budgetAnalysisDataTableId” 当财政年度结束或无效时，它将成功处理 但是，当财务年度开启时，它不会生成p：dataTable id =“budgetAnalysisDataTableId值”
但是当我把
<p:tabView id="scenarioTabViewId" style="width:850px" >
<p:tab title="Scenario One" id="scen">
<p:dataTable id="budgetAnalysisDataTableId" editable="true" scrollable="true" scrollWidth="800" resizableColumns="true" value="#{budgetAnalysisAction.budgetScenarioHescoProposalBean.budgetScenarioHescoProposalListBean}" var="budgetScenarioHescoProposalList">
… HERE ARE SOME COLUMNS
</p:dataTable>
</p:tab>
</p:tabView>
以外的
<h:panelGrid columns="2" id="isFinancialYearBooleanPanelGridId" styleClass="panelGridCenter" >
p：dataTable对我来说很好用
任何想法谢谢（Y）

答案 0 :(得分：0)
我想将此添加为评论，但也许我发现了您的问题：
在p：commandbutton中你有：
update="isFinancialYearBooleanPanelGridId scenarioTabViewId:budgetAnalysisDataTableId"
不应该（你吃结肠吗？）
update="isFinancialYearBooleanPanelGridId:scenarioTabViewId:budgetAnalysisDataTableId"
答案 1 :(得分：0)
我使用
解决了我的问题的.java
RequestContext requestContext = RequestContext.getCurrentInstance();
requestContext.addCallbackParam("budgetFinancialYearBean", this.budgetFinancialYearRefObj);
.xhtml
<p:commandButton id="isFinancialYearSubmitId" value="submit" update="panelGridId scenarioTabViewId:budgetAnalysisDataTableId" action="#{budgetAnalysisAction.isFinancialYearOpened}" oncomplete="handleComplete(xhr, status, args); isFinancialYearOpenedOnComplete();"/>
的.js
function handleComplete(xhr, status, args) {
var financialYearForProposalsBeanVar = args.budgetFinancialYearBean.financialYearForProposalsBean;
if(financialYearForProposalsBeanVar == 1) {
//rendering data table
// alert('value: '+financialYearForProposalsBeanVar);
document.getElementById("budgetAnalysisDataTableDivId").style.display = "block";
}
}
