generated pdf file contents are cached

[ehsmurali]

Hi,
   I am trying to publish the user information as a downloadable pdf file when clicked on a link(s:link) named print. Eveything works fine, the data pertaining to the clicked link get exported as pdf. However, the same information is published eventhough the user clicks on a different link.

   The report published for the first clinked link is getting cached for the subsequent links.

Here is the code, that publishes the report.

try {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        Renderer renderer = Renderer.instance();
        renderer.render(facelet);

        DocumentStore store = DocumentStore.instance();
        DocumentData data = store.getDocumentData("1");
        HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
        String fileName = makeUniqueFileName();
        response.setContentType("application/pdf");
        response.setHeader("Content-disposition", "attachment; filename=\"" +String.valueOf(new Random().nextInt())+ ".pdf"+"\"");
        response.setHeader("Pragma", "");
        response.setHeader("Cache-Control","no-store");

        ServletOutputStream os;
        try {
                os = response.getOutputStream();
                data.writeDataToStream(os);
                os.flush();
                os.close();
                facesContext.renderResponse();
        } catch (Exception e) {
                FacesMessages.instance().addFromResourceBundle( "reportCouldNotBeGenerated");
        }

} catch (Exception ex) {
        ex.printStackTrace();
}

I'm sorry if this is really off base but,

DocumentData data = store.getDocumentData("1");

that looks pretty static to me as to which document is going to get returned. The documentStore is a conversation scoped component. So unless each link is in a brand new conversation then the I fail to see how using getDocumentData(1) is going to work.

Hmm, been reading the code of DocumentStore a bit more. Can you post the code where you put the document into the store? Are you always doing store.saveData(1, document) ? If you are doing this then I'm not really sure. I can't see the documentStore doing anything fancy.

Maybe try remotely debugging and see if your document is actually getting stored in the DocumentStore?
