Yes, I only get one call on startup, but at that call the page returned
by getSelected has two children (so I suspect the page returned by
getData will be the same page and so I'll still see two children).
I'm OK, I just threw in a hack to always take the last child. :) But if
"changeSelected" is being called before the widget is ready, folks may
run into other problems eventually.
thx, kenny
