[Laszlo-dev] ERROR: Attempt to instantiate <foo>, which has not been defined

[Sarah Allen]

I was trying to isolate a bug where the type setter wasn't being called 
for videoview with the test file below.  The dynamic class/interface 
stuff is new for me.  Can someone tell me what I did wrong?

I get this runtime error in the debugger:
	ERROR: Attempt to instantiate <foo>, which has not been defined
