Component nesting broken in beta.1 #6404

While updating to beta.1, I encountered an error with nested components. Depending on the order I use the components, it fails unexpectedly with the following error:

EXCEPTION: TypeError: viewFactory_BlueBox0 is not a function.

This may be related to the change in 7ae23ad

I reproduced the error in this plunkr:
