As I mentioned in my previous response, I couldn't use
getRequestCycle().setRequestTarget() directly because of the way the API
works (you can use a ResourceReference but not a Resource.) Instead, I
ended up with something like this:
new AjaxButton(buttonId, form) {
protected void onSubmit(AjaxRequestTarget target, Form form) {
ResourceReference pdfReference = new ResourceReference("") {
protected Resource newResource() {
return new BillPdfWebResource(...);
}
};
String url =
getRequestCycle().get().urlFor(pdfReference).toString();
getRequestCycle().setRequestTarget(new
RedirectRequestTarget(url) );
}
}
It works... but only once. When I click on the button, everything works, my
PDF gets generated and downloaded but then my app becomes unresponsive. I
can't interact with the site at all until I "start over." Is there a better
way to go about this that wouldn't cause that side effect? Whatever
approach I take, I need to be able to submit a form when the PDF is
generated. My example doesn't show it but my BillPdfWebResource class
generates a PDF based on the user's selection and my Form's Model needs to
be updated. Any suggestions?
