WAStateHolder

Seaside-StateRegistry

Comment: 

I am a ValueHolder whose contents will properly track the user's use of the back button.  Use me to wrap any values that you wish to backtrack when the back button is used.

Sometimes it might be more convenient to register your business object directly:

	WACurrentSession value registerObjectForBacktracking: businessObject.

or even to register a component for backtracking, as seen in WACounter:

	WACounter>>initialize
		self session registerObjectForBacktracking: self.
