Open file from ADF pages gives a problem

Question

Hi all,
I have created with Jdev 11g an ADF page.
In that page is shown a table with the files that are stored in the database.
I use this code to show the file:
    public void showFile(BlobDomain  b,String filename){
        FacesContext fc = FacesContext.getCurrentInstance(); 
        HttpServletResponse response = (HttpServletResponse)fc.getExternalContext().getResponse();
        response.setHeader("Content-Disposition","attachment; filename=\""+filename+"\"");
        response.setHeader("cache-control", "no-cache");
        try {
            InputStream in;
            in = b.getInputStream();
            ServletOutputStream out = response.getOutputStream();
            writeInputStreamToOutputStream(in, out);
            fc.responseComplete(); 
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Throwable e) {
            e.printStackTrace();
    }This works for the first time a file is opened. But when the user then selects a different row nothing is happening anymore.
What can that be?

Hi Simon,
This is the button:
                  <af:commandButton text="Open file"
                                    binding="#{backingBeanScope.backing_pages_Meldingen.cb5}"
                                    id="cb5"
                                    disabled="false"
                                    action="#{backingBeanScope.backing_pages_Meldingen.openFile}"/>this is openfile:
    public String openFile() {
        BindingContainer bindings = this.getBindings();
        DCIteratorBinding iter = (DCIteratorBinding)bindings.get("XxahelpBezoekRapDocView1Iterator");
        Row currentRw = iter.getCurrentRow();
        showFile((BlobDomain)currentRw.getAttribute("Bijlage"),currentRw.getAttribute("Filename").toString());
        return null;
    }And how can I download in a popup??
