jsf - Can not generate p:datatable in h:panelgrid values on ajax p:commandbutton update

Question

I am developing a project in JSF2.1 ,prettyfaces, hibernate 4 , primefaces I am getting a problem here… I ve one p:commandbutton which calls ajax request where condition checks that, financial year is opened or not

<p:commandButton id="isFinancialYearSubmitId" value="submit"  update="isFinancialYearBooleanPanelGridId scenarioTabViewId:budgetAnalysisDataTableId" action="#{budgetAnalysisAction.isFinancialYearOpened}"  oncomplete="isFinancialYearOpenedOnComplete();"/>

There are 3 value… if financial year is opened then ‘1’ if financial year is closed then ‘0’ if invalid then ‘ -1’ If financial year is closed or invalid then an image is loaded with some text ,but problem is here If financial year is opened then I want to generate a 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="&lt;div class='n_error'>&lt;p>Error . #{budgetAnalysisAction.util.errorMessage}&lt;/p>&lt;/div>" escape="false"/> 
</ui:fragment>
</ui:fragment>
<ui:fragment rendered="#{budgetAnalysisAction.budgetFinancialYearBean.financialYearForProposalsBean == '0'}">
<ui:fragment rendered="#{budgetAnalysisAction.util.errorCode == '-1'}" >
<h:outputText  value="&lt;div class='n_error'>&lt;p>Error . #{budgetAnalysisAction.util.errorMessage}&lt;/p>&lt;/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>

When I submit the command button update=” isFinancialYearBooleanPanelGridId scenarioTabViewId:budgetAnalysisDataTableId” It will process successfully when financial year is closed or invalid But it will not generate p:dataTable id="budgetAnalysisDataTableId values when financial year is opened

but when i put

<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>

outside the

<h:panelGrid columns="2" id="isFinancialYearBooleanPanelGridId" styleClass="panelGridCenter" >

p:dataTable works fine for me

Any idea thanks (Y)

我想将此添加为评论，但也许我发现了您的问题：

在 p:commandbutton 你有：

update="isFinancialYearBooleanPanelGridId scenarioTabViewId:budgetAnalysisDataTableId"

不应该是（你吃结肠了吗？）

update="isFinancialYearBooleanPanelGridId:scenarioTabViewId:budgetAnalysisDataTableId"

我已经解决了我的问题

.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();"/>

.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";    
    }

}

jsf - Can not generate p:datatable in h:panelgrid values on ajax p:commandbutton update
