Hi,

In my page i have Export as Excel link at the outside datatable.

<a4j:commandLink value="Export as Excel"

        rendered="#{reporting.selectedTab.equals('shortIdSearch')}"

        action="#{reporting.generateExcelByShortID()}"

        oncomplete="if(#{facesContext. maximumSeverity==null}) {#{rich:component('confirmExcelModel')}.show();}"/>

Here i am showing an popup,Inside popup which tells - Excel API only supports 65,535 rows.Would you like to download first 65,535 rows?

I have tried with 2 options for downloading the excel file using jxl API.

1.Normal a4j:commandButton  -- Able to download excel file but oncomplete popup is not closing.

2.Seam WebRemoting - Not calling the backing bean.But popup is not closing and loading image is also not closing on oncomplete method.

Added below code in the .xhtml page:

<script type="text/javascript" src="seam/resource/remoting/resource/remote.js"></script>

    <script type="text/javascript" src="seam/resource/remoting/interface.js?reporting"></script>

    <s:remote type="text/javascript" include="reporting"/>

<a4j:region id="popupExcelRegion">

            <rich:popupPanel id="confirmExcelModel" autosized="true" modal="true" domElementAttachment="parent">

                <f:facet name="header">

                    <h:outputText value="Excel only supports..." />

                </f:facet>

                <f:facet name="controls">

                    <h:panelGroup>

                        <h:graphicImage value="/img/close.png" id="hidelinkDelete"

                            styleClass="hidelink">

                            <rich:componentControl target="confirmExcelModel" operation="hide"

                                event="click" />

                        </h:graphicImage>

                    </h:panelGroup>

                </f:facet>

                <h:form id="confirmExcelForm" onsubmit="return false;">

                    <a4j:region id="confirmExcelModelRegion">

                        <a4j:outputPanel id="popupExcelpanel" ajaxRendered="true">

                        <h:messages/>

                        <rich:messages/>

                        <div align="center">                  

                                <h:graphicImage value="/img/msgwarn.png" />

                                <h:outputText

                                    value="Excel API only supports 65,535 rows.Would you like to download first 65,535 rows?" escape="false" />                          

                                <h:panelGrid columns="2">                                                              

                                <button type="button" onclick="downloadExcel();">Yes</button>                               

                                <a4j:commandButton value="Yes" action="#{reporting.generateExcelLimitedByShortIDNew}"

                                      execute="@form" render="@form"

                                      oncomplete="if(#{facesContext.maximumSeverity==null})#{rich:component('confirmExcelModel')}.hide();">                                       

                                </a4j:commandButton>                                                                        

                                <a4j:commandButton size="20" value="No" status="statusExcelIDs"                              

                                        onclick="#{rich:component('confirmExcelModel')}.hide();return false;" />                                                              

                                </h:panelGrid>                              

                                </div>              

                        </a4j:outputPanel>

                    </a4j:region>

                </h:form>

            </rich:popupPanel>

        </a4j:region>

<script type="text/javascript">

  function downloadExcel() {

   Seam.Component.getInstance("reporting").generateExcel('help',closeExcelpopUp); //Not even calling backing bean method "generateExcel()"

  }

  function closeExcelpopUp() { 

         Richfaces.hidePopupPanel("confirmExcelModel");

  }

</script>

Backing bean class:

@Name("reporting")

@Scope(ScopeType.CONVERSATION)

public class Reporting {

......

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

@WebRemote  

    public String generateExcel(String helpValue) {     

        this.shortIdReportExcel = null;

        if(this.shortIdReport.size()>65534){

            this.shortIdReportExcel= this.shortIdReport.subList(0,  65532);        

        }else {

            this.shortIdReportExcel= this.shortIdReport;    

        }          

        return "/layout/shortid-excel.xhtml";

    }

    public String generateExcelLimitedByShortIDNew() { 

        this.shortIdReportExcel = null;

        if(this.shortIdReport.size()>65534){

            this.shortIdReportExcel= this.shortIdReport.subList(0,  65532);       

        }else {

            this.shortIdReportExcel= this.shortIdReport;        

        }          

        return "/layout/shortid-excel.xhtml";

    }

}

By Implementing the below code popup is closed.But after downloading the excel file ,I cannot do any click operations and nothings i can do in the screeen.Looks like screen is locked?

<a4j:commandButton value="Yes" action="#{reporting.generateExcelLimitedByShortIDNew}" status="statusExcelIDs"

                                      execute="@form" render="@form"

                                      onbegin="#{rich:component('confirmExcelModel')}.hide();">                                       

                                </a4j:commandButton>

Looks like this CORE RF BUG in the version?
