Re: [Rubycocoa-talk] validateValue:forKey:error: problem

Whoops, I'll try that again.  Previous attempt inadvertently in HTML;  
sorry for the spam.

A week or so ago I said:

On the off chance that this means nobody happens to know and this is a  
real problem, here's my workaround:

I overloaded validateValue:forKey:error:, for now in the Ruby class  
with the properties I'm validating:

	def validateValue_forKey_error(value, key, error)
		selector = "validate" + key.capitalize + "_error"
		if (self.respond_to? selector)
			return self.send(selector, value, error)
		else
			return true
		end
	end

If this is, indeed, a real problem, something like this could go into  
the Ruby NSObject code.  Better would be to fix it in the objc  
NSObject code, but there's that pesky lack of source code...

Again, I'm using the Ruby/RubyCocoa that came with Leopard.
