Answer 1

When partially refreshing a XPage, the datasources are not reloaded, only their last state (stored in memory or hdd ) is restored. If you change the scope of your datasource to request, the XPages engine is forced to recreate the datasource instead of using the cached one on each request (which includes partial refreshs).

This should allow you to refresh your fileDownload control without a full refresh.

The link is fairly old, but I believe it still applies.

Matt White says in the article comments: "...Basically it is not currently possible to post a file attachment over AJAX, you either have to use Flash or a virtual iFrame solution if you don't want the entire page to refresh. As far as I know there is nothing that IBM can do about this at the moment. Matt"
