Couldn't find a superclass implementation of TreeGrid.undefined

[evanross]

I have an app which compiles cleanly in Eclipse, but when I run it I am getting the following error. I'm guessing that I'm missing something in my runtime config but can't tell what. Any clues?

I'm using GWT 2.2, SmartGWT Power 2.4
