[Seaside] Problem with callback blocks sharing context using closure image

[Bob Arning]

Actually, that would not work as written in a closure image. To make it 
work in closure image, you could write something like:

...
	aRenderer anchor
		callback: (makeCallBackWith: index );
...

And then write a method

makeCallBackWith: n
	^[self callbackFor: n]


In a non-closure image, it would work as written since fixCallbackTemps 
would have been sent automatically.

Cheers,
Bob
