You can delete a post using the button on the post, but you cannot edit it.
If you send your request as an RPC, then you expect to get an RPC response.
If the response instead is sending different mime headers (to popup a
download prompt on the browser), I'm pretty sure GWT will throw an error.
That is why I was saying you would want to trigger this with a form POST to
your servlet, not an RPC request, since the POST can open a download prompt.
