Af:fileDownloadActionListener picks wrong filename for the first time after row selection.

Question

Hi,
I am using Oracle Jdeveloper 11g release 1. In one of my jspx pages i have a table, i can select one of the row and click on a button which invokes fileDownloadActionListener. The code of jspx is as below:
<af:commandMenuItem text="#{coregccomplianceuiBundle.MENU_EXPORT}"
                                    id="CS19" partialSubmit="true"
                                    actionListener="#{viewScope.core_gccompliance_cs_librarybean.validateExport}"
                                    partialTriggers="CSftLib"
                                    disabled="#{viewScope.core_gccompliance_cs_librarybean.exportDisabled}">
</af:commandMenuItem>
<!--This button is set hidden, which is used to deal with the download job.
    The Export button on the page only does the validation. (whether it's a system defined standard)-->
  <af:commandButton text="#{coregccomplianceuiBundle.BTNEXPORTHIDDEN}" id="csl_csExportHidden"
                                      clientComponent="true" visible="false"
                                      partialSubmit="false">
<af:fileDownloadActionListener contentType="application/x-download" 
                                      method="#{viewScope.core_gccompliance_cs_librarybean.handleExport}"
                                      filename="#{viewScope.core_gccompliance_cs_librarybean.fileName}"/> 
</af:commandButton>
  /** force the ExportHidden Button to do export */
    function csExportHandler(event) {
        var exportCmd = AdfPage.PAGE.findComponent("emT:CS4:csl_csExportHidden");
        var actionEvent = new AdfActionEvent(exportCmd);
        actionEvent.forceFullSubmit();
        actionEvent.noResponseExpected();
        actionEvent.queue();
The bean methods used in above block are as below:
public void validateExport(ActionEvent actionEvent) {
       // checks if entity is system defined and shows error popup if it is .
        if (checkIsSystem())
            return;
        //Handle the export    
        AdfUtil.addScript("csExportHandler()");
public void handleExport(FacesContext context, OutputStream out) {
        ComplianceLibraryAMImpl am = getDataController();
        HttpServletRequest request =
            (HttpServletRequest)context.getExternalContext().getRequest();
        Locale locale = NLSUtil.getClientLocale(request);
        ResourceBundle rb =
            ResourceBundle.getBundle("oracle.sysman.core.gccompliance.view.CoreGccomplianceUiMsg",
                                     locale);
        PreparedStatement st =
            am.getDBTransaction().createPreparedStatement("commit", 1);
        Connection conn = null;
        boolean isAgentSideCs = false;
        try {
            conn = st.getConnection();
            RichTable oTable = getCsTable();
            fileName = "ComplianceStandard.xml";
            List<Raw> exportGuids = new ArrayList<Raw>();
            for (Object opaqueFacesRowKey : oTable.getSelectedRowKeys()) {
                oTable.setRowKey(opaqueFacesRowKey);
                Object o = oTable.getRowData();
                JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)o;
                exportGuids.add((Raw)rowData.getRow().getAttribute("CsGuid"));
                int csType = ((oracle.jbo.domain.Number)rowData.getRow().getAttribute("CsType")).intValue();
                if(csType == 4)
                    fileName =
                            (String)rowData.getRow().getAttribute("CsDname") + ".zip";
                    isAgentSideCs = true;
                else
                    fileName =
                            (String)rowData.getRow().getAttribute("CsDname") + ".xml";
                if(((Integer)rowData.getRow().getAttribute("IsSystem")).intValue() == 1){
                    throw(new ParseException(50));
            if (exportGuids.size() > 1)
                fileName = "Compliancestandard_list.xml";
            RAW guid = new RAW(exportGuids.get(0).toString());
            if(isAgentSideCs)
                getDataController().exportStandardContent(conn, out, guid);
            else
                CsExport csexport = new CsExport(false);
                csexport.doCsExport(conn, guid, false, out);
        } catch (ParseException e) {
            String errMsg = "";
            String errHdr = "";
            if(e.getStatus() == 50){
                errMsg = rb.getString("ERRMSG_ISSYSTEMENTITY_EXPORT");
                errHdr = rb.getString("ERRHDR_ISSYSTEMENTITY_EXPORT");
            else{
                errMsg = rb.getString("ERRMSG_EXPORT_CS");
                errHdr = rb.getString("ERRHDR_EXPORT_CS");
            AdfUtil.showMessageDialog(null, AdfUtil.MESSAGE_TYPE.ERROR, errHdr,
                                      errMsg, false, null);
            throw new RuntimeException(e);
        } catch (SQLException e) {
            throw new RuntimeException(e);
        } finally {
            JDBCUtil.close(st);
        MimeUtil mimeUtil = new MimeUtil();
        mimeUtil.downloadFile(context, fileName);
        try {
            out.flush();
            out.close();
        } catch (IOException e) {
            throw new RuntimeException(e);
Class MimeUtil:
public void downloadFile(FacesContext context, String fileName) {
        HttpServletResponse httpServletResponse =
            (HttpServletResponse)context.getExternalContext().getResponse();
        HttpServletRequest httpServletRequest =
            (HttpServletRequest) context.getExternalContext().getRequest();
        String unicodeFileName = fileName;
        String agent = httpServletRequest.getHeader("USER-AGENT").toLowerCase(Locale.US);
        boolean isIE = false;
        if (null != agent && -1 != agent.indexOf("msie"))
            isIE = true;
        //encode the output file name to support NLS
        unicodeFileName = MimeUtil.encodeFileName(fileName, isIE);
        httpServletResponse.setHeader("Content-disposition",
                                      "attachment;filename=\"" + unicodeFileName +
httpServletResponse.setContentType("application/x-download");
        context.responseComplete();
        httpServletResponse.setContentType("application/x-download");
        context.responseComplete();
Now when i come to the page for first time and select a row and click on Export then the filename that gets shown in save file dialog is incorrect (it shows partial adf taskflow name) , but when i select the row again by clicking on any other row and click export it shows correct filename i.e. selectedRowName.zip or .xml according to type of row selected.
Can anybody suggest what am i missing?

Answer 1

difficult to tell like this.but better you debug your code then you can get where you getting filename wrong.
