Filedownload and progressbar

Hi all,

One of my backingBeans contains a method that returns a file for download.

This is working fine and the standard Open/Save/Cancel box pops up. No problem.

In addition I display always a "work on progress message" with a _javascript_ call when my form is submitted (onSubmit).

The problem is now that I don't know how to disable this message again when the file is ready for download.

There is no event on which I can react in the browser. The original page is not reloaded (and should not be reloaded).

Can I use a second jsp which calls the showOriginalDocument action and does a _javascript_ call in the parent window (or openener)?

Does anybody have an idea?

JSP:

<h:commandLink action="" immediate="true">

<t:graphicImage url="" />

</h:commandLink>

BackingBean:

public void showOriginalDocument() {

NativeDocument nativeDocument = this.delegate.getOriginalDocument(this.document.getDocumentId());

HttpServletResponse response = (HttpServletResponse)facesContext.getExternalContext().getResponse();

response.setContentType(nativeDocument.getMimeType());

response.setHeader("Content-Disposition","attachment;filename=\""+ this.document.getAttribute("docnumber")+nativeDocument.getSuffix() + "\"");

response.setContentLength(nativeDocument.getDocument().length);

OutputStream responseStream = ((HttpServletResponse)facesContext.getExternalContext().getResponse()).getOutputStream();

responseStream.write(nativeDocument.getDocument());

response.flushBuffer();

facesContext.responseComplete();

Michael
