The "Expand" event doesn't seem to be firing on the 'Collapsible' control. I've tried expanding it both by clicking on it and programmatically, but nothing. Is it working for everybody else?
Actually, digging a bit deeper, none of the events on this control seems to be firing. I haven't tried them all, but Expand, Collapse, Tap, Click, Focus and Selected are not firing for me.
These events seem to be working now, since I upgraded the MAB this morning.
