This is a place for us to start seriously talking about vendors. Who's great, who's not, what's it cost, how does it relate to their competitors and would we buy it? A place to talk about snakeoil, and brilliant products alike. Marketing fluff is forbidden.
Anyway, Javeline Platform is an AJAX framework which integrates XML and JavaScript and melts them into their own JSL syntax. I've been playing around with it for a few days learning the syntax and properties of different containers/components. There isn't much support at all, and it takes a steely resolve to sit through hours of wondering "why on earth has my list suddenly stopped displaying data", but this could be quite a powerful tool (if only they had decent tutorials, a manual and a forum), especially when they release another product they're working on, DeskRun (allows you to package a full zip of your web app and convert it into an exe which can access the filesystem and act like a normal windows app - very nifty). Anyway, just thought I'd let you guys know in case you wanted to take a look and try and build a few things with it.. Its easy to learn, just frustratingly fragile (the littlest things stop your xml data from actually converting and being listed properly.... UGH).
Ruben has some articles on his blog http://www.rubendaniels.com and there is a reference guide on the developer site. I agree though that a few more tutorials and better documentation wouldn't hurt.
I anycase, just ask a question on the mailinglist at http://developer.javeline.net/mailinglists.php. Most of us are also quite new to JPF, but we'll manage.
