There is a good document at:
as html:            http://www.mk.dmu.ac.uk/~gperkins/Smalltalk/State/
as word doc:    
http://www.mk.dmu.ac.uk/~gperkins/Smalltalk/State/Statepat.doc

it uses the state pattern, which i would strongly prefer. but it is 
explained very good in the document.

regards marco
