Java EE (Java Enterprise Edition) General Discussion

Hello there:

I am trying to download a dynamically generated file.
It is not a real file I have in the server, but an "Apache POI HSSFWorkbook", which can be downloading by the client as an excel sheet (HorribleSpreadSheetFormat :).

The download method is in a action-methode which I call from one page. I have to present the "download-Mask" and (after the download or the cancel) return to the same page.
So far so good and working well. I can open the downloaded file and it is all ok.
BUT
My problem is when I try to use another "action method" in that page (after the download)
it comes again the "download-Mask" !!
even if that has nothing to do with this other "action method".

So: something not closed? I try many other ways with no result...


CODE:

faces-config:

...
<managed-bean>
  <managed-bean-name>downloadActions</managed-bean-name>
  <managed-bean-class>jsfApp.logic.DownloadActions</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope></managed-bean>
...  
<navigation-rule>
  <from-view-id>/asls.jsp</from-view-id>
    <navigation-case>      
      <from-outcome>process</from-outcome> <!-- the other feature on that page-->      
      <to-view-id>/asls.jsp</to-view-id>    
    </navigation-case>    
    <navigation-case>    
      <from-outcome>download</from-outcome> <!-- the d/l feature-->    
      <to-view-id>/asls.jsp</to-view-id>    
    </navigation-case>    
    <navigation-case>    
      <from-outcome>err</from-outcome>    
      <to-view-id>/errs.jsp</to-view-id>    
    </navigation-case>  
</navigation-rule>
...

downloadMethod:
(as written above I already used other ways like: the write method from HSSFWorkbook, or other dispositions, etc.)

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

// text/plain   vnd.ms-excel    application/x-download
response.setContentType("vnd.ms-excel");
response.setHeader("Content-disposition","attachment; filename=\"myHSSF.xls\"");		
ServletOutputStream out; 
try {  
  out = response.getOutputStream();  
  out.write(theBytes);  
  out.flush();
}
...
faces.responseComplete();
...

page:

<h:commandLink id="expexcel" action="#{downloadActions.downloadMethod}" value="download"/>

Any ideas?
Thanks!
