Touchkit 3 TabBarView display issues

Hi, I am constructing an app using the new touchkit 3 API. There seems to be a problem with the TabBarView (which worked fine in previous versions), where the tab toolbar is rendered off the bottom of the screen. It seems that for some reason the content area is getting the full 100% screen space rather than taking the tab bar into account. I can get it to show if I manually set the height of the TabBarView component, but this is a hack I don’t like.

Is there a fix for this, or otherwise an elegant workaround??

Thanks.

I am having exactly the same issue. Any ideas anyone?
