If I had to guess, I guess it's trying to evaluate the "set" command (implemented by NSSetCommand), but somehow it's gotten the notion that a different cocoa class (empty string?) has been configured as the handler for that type.

The ways of AppleScript remain dark and mysterious. After implementing add <object> to <container> and remove <object> from <container> I noticed that if <object> was a singular medium, it would ignore the implementation class named for the command and only call the implementation method for medium's respond-to. However, if <object> was a plural (i.e. list of) media it would only call the class and not the method.

To put it another way:

tell libraryDocument to add someMedium to someShelf

calls:

someMedium -implementationMethod:

while:

tell libraryDocument to add someMedia to someShelf

calls:

ImplementationScriptCommand -performDefaultImplementation

I kind of expected one or the other to be called on the object receiving the tell, but in fact, not only is that not the case, I can't figure out a way to figure out who received the tell at all. I had thought:

tell someShelf to add someMedium

would be a good alternate form, but I could see no way to get someShelf out of the resulting NSScriptCommand.
