RE: DownloadLink problem
Oh my God!!! The problem was that the button that is supposed to do the export
was of type submit and it reloads the page, instead of refreshing components. I
changed to type=button and everything's fine...
As people say - there is no patch for human stupidity...
Thank you all for the help!

Not sure... but could you try something like:

downloadLink.setOutputMarkupId(true);
