ViewLoop question

Hi, has anyone tried ViewLoop yet? When I follow the example and push View loop over existing view, everything works ok, unfortunately, when I try to use it as first view in getInitialView, the app crashes when I return instance of ViewLoopDelegate as initial delegate.

Error: Unexpected Type Error

Interestingly I can create dummy view and in its onShow call switchToView with ViewLoop, which works.

What can be wrong, that it behaves in such way?
