XML Publisher - Page Hangs on clicking export button

Question

Hi,
I have a requirement to open a pdf file from xml publisher report on click of a button. I captured the event of the submitButton and wrote the code as follows:
if("Event.Submit".equals(s1)){
OAApplicationModule am = (OAApplicationModule)pageContext.getRootApplicationModule().findApplicationModule("XXAM");
XMLNode xmlNode = (XMLNode)am.invokeMethod("getQuoteDataXML");
// Get the HttpServletResponse object from the PageContext. The report output is written to HttpServletResponse.
DataObject sessionDictionary = (DataObject)pageContext.getNamedDataObject("_SessionParameters");
HttpServletResponse response = (HttpServletResponse)sessionDictionary.selectValue(null,"HttpServletResponse");
try{
ServletOutputStream os = response.getOutputStream();
// Set the Output Report File Name and Content Type
String contentDisposition = "attachment;filename=ABC.pdf";
response.setHeader("Content-Disposition",contentDisposition);
response.setContentType("application/pdf");
// Get the Data XML File as the XMLNode
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
xmlNode.print(outputStream);
ByteArrayInputStream inputStream = new ByteArrayInputStream(outputStream.toByteArray());
ByteArrayOutputStream pdfFile = new ByteArrayOutputStream();
//Generate the PDF Report.
TemplateHelper.processTemplate(
((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getAppsContext(),
"ASO",
templateCode,
((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getUserLocale().getLanguage(),
((OADBTransactionImpl)pageContext.getApplicationModule(webBean).getOADBTransaction()).getUserLocale().getCountry(),
inputStream,
TemplateHelper.OUTPUT_TYPE_PDF,
null,
pdfFile);
// Write the PDF Report to the HttpServletResponse object and flush.
byte[] b = pdfFile.toByteArray();
response.setContentLength(b.length);
os.write(b, 0, b.length);
os.flush();
os.close();
}catch(Exception e){
response.setContentType("text/html");
throw new OAException(e.getMessage(), OAException.ERROR);
pageContext.setDocumentRendered(false); // I'm not sure why, but found something similar online
The download window opens properly. But, the mouse icon is changed to hourglass and I cannot click on anything. I have to move to any other window in my system and comeback to this page to click on the save button. Also, once the file is downloaded I cannot click on anything on that page. I have to use browser back button to go back to previous page.
Really appreciate any help to solve this issue.
Thanks,

Reetesh,
No, this is not completely custom development. I have to invoke a custom report from a seeded page. And there happens to be button bean on it.
If u look at the code above, I'm already trying to capture a fireAction event (Event.Submit) and trying to launch the report. But it doesnt work.
Please let me know of any other suggestions you have to make this work.
Thanks,
Bharath
