Hello Jakob, I am very interested in this feature. I would like to be able to join on an abstract extent class (spanning multiple tables) someday. I've only recently attempted this, and quickly found that it doesn't currently work. I then found your related email. It seems like a separate query for each extent-class table would be required for this to work.
