[Seaside-dev] Issue with #removeDecoration:

[John Thornborrow]

Changeing #removeDecoration to the below seems to have fixed it.. not 
extensively tested (nor is it particularly elegant.)

Would this cause any issues that anyone can think of? (note the use of 
#respondsTo:)

removeDecoration: aDecoration
	| dec |
	dec := self decoration.
	dec = aDecoration ifTrue:
		[self decoration: dec owner.
		^ self].

	[dec notNil and: [dec respondsTo: #owner]] whileTrue:
		[dec owner = aDecoration
			ifTrue: [dec owner: aDecoration owner.  ^ self]
			ifFalse: [dec := dec owner]]
