XPages does not run in NTF

I got a problem: XPages could not be opened from .NTF in the client

"XPages cannot process the application launch page: notes:///discussion8.ntf/allDocuments.xsp?OpenXPage"

I suppose this could be because of .NTF could not be opened on the web also, so Lotus does not run HTTP to process XPage for the client.

So .NTF becomes useless for development because of you could not test what you are doing immediately.
