PDF Component

Question

Hi,
I have a component that is intended appear in one state and display various PDFs. I have it working when it is called the first time, however when it is called subsequently it does not load the PDF.
I have been using the Tour de Flex approach of using a mx:HTML to show the PDF, but changed to adding elements to a spark container:
private var pdfHTMLLoader:HTMLLoader = new HTMLLoader();
private var pdfUIC:UIComponent;
                              private function loadPDF():void {
  // Check to see if Adobe Reader 8.1 or higher is installed
  // Possible values:
  //         HTMLPDFCapability.STATUS_OK
  //         HHTMLPDFCapability.ERROR_INSTALLED_READER_NOT_FOUND
  //         HTMLPDFCapability.ERROR_INSTALLED_READER_TOO_OLD
  //         HTMLPDFCapability.ERROR_PREFERRED_READER_TOO_OLD
                                        if(HTMLLoader.pdfCapability == HTMLPDFCapability.STATUS_OK) 
  // Use FlexGlobals variable for PDF name
                                                  var pdfRequest:URLRequest = new URLRequest(FlexGlobals.topLevelApplication.currentPDF);
                                                  pdfHTMLLoader = new HTMLLoader();
                                                  pdfHTMLLoader.width = pdfWin.width;
                                                  pdfHTMLLoader.height = pdfWin.height;
                                                  pdfHTMLLoader.load(pdfRequest);
                                                  pdfUIC = new UIComponent();
                                                  pdfUIC.addChild(pdfHTMLLoader);
                                                  pdfUIC.name = "PDFView";
                                                  pdfWin.addElement(pdfUIC); // Add the element to the pdfWin spark container
                                        } else {
                                                  Alert.show("PDF cannot be displayed. Error code:" + HTMLLoader.pdfCapability);
  // Called if window is resized
                              private function reloadPDF():void {
                                        pdfHTMLLoader.width = pdfWin.width;
                                        pdfHTMLLoader.height = pdfWin.height;
                                        pdfHTMLLoader.reload();
                              protected function backButton_clickHandler(event:MouseEvent):void
                                        pdfWin.removeAllElements();
                                        flash.system.System.gc();
                                        var eventObject:Event = new Event("hidePDF");
                                        dispatchEvent(eventObject);
I think that the problem may be in either removing the elements or in how I am adding the HTMLLoader to the UI Component and then adding the element to the spark container.
Thanks,
Niall

You could have a page on host1 that collects the data and
outputs it as
XML, then on host2 it uses the XML to create the PDF.
