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

[Sarah Allen]

The a/v extensions are written this way (I didn't write them).  Their 
setters aren't being called which make the test files not work.  I was 
trying to isolate why the setter wasn't called, so I wrote that test 
file.  Max worked around the bug we were seeing this morning in the 
change I approved earlier.  We figured the best thing is to refactor all 
of the a/v extensions with LZX syntax as they used to be. 

Is there anywhere else that private internal protocol is used? If so, 
there may be other bugs as a result of those changes.

Thanks,
Sarah
