Hi Andy, first of all, thanks for looking at and merging the other patches.

Whilst you're in the flow, I thought I'd re-iterate this little issue - when you call TabPane.tabs() in Javascript you get:

sys::CastErr: fwt::Widget[] cannot be cast to fwt::Tab[]

I mentioned it in `http://fantom.org/forum/topic/2453#c3` because I suspect it's part of a larger type cast problem. But as a workaround until that gets addressed, it'd be cool if you could look at incorporating this patch (if appropriate):
