Bug when scrolling clickableGroup

What steps will reproduce the problem?
1. Take the MadGroups example and copy/paste the clickableGroup block a few 
times so that the content is too long for the screen.

2. directly after the opening vertical tag of CONTACTS add a scrollVertical - 
close it just before the last line of XML (close vertical tag)

3. Run the app and scroll up and down.

What is the expected output? 
The screen scrolling up and down with no errors.

What do you see instead?

A fairly regular error (particularly easy to trigger if you click on the 
background near the three buttons)

TypeError: Error #1010: A term is undefined and has no properties.
