Re: [Wonder-disc] EntityModeler and Prototypes loading question

[Mike S. <ms...@md...>]

Ah .. here's the "why". This is a question for Lachlan ... I don't  
know if this was a merge problem or, if not, why he's piggy-backing on  
patchesModelOnLoad, which I can't imagine ever actually wanting turned  
on.  You could also set er.extensions.ERXModelGroup.modelClassName to  
the Model class explicitly.  I'm not sure we shouldn't default to  
that, actually?
