[Seaside] Validation problem -- missing package?

[Peter Kwangjun Suk]

I'm getting a funny validation error in Magritte.

Is the "Scaffolding" package necessary to restore extensions like
#isKindOf: in the Memento classes?


MADescription>>validateKind:
validateKind: anObject
	"Validate ==anObject== to be of the right kind."

	(anObject isKindOf: self kind)
		ifFalse: [ MAKindError description: self signal: self kindErrorMessage ]
