[Seaside-dev] Issue with #removeDecoration:

[John Thornborrow]

Forgot to add, that this indicates that #decoration: is not always 
sent.. am yet to find out why it wouldn't be sent yet, or perhaps 
#initializeDecoration should do more than just "decoration := 
WAValueHolder with: self", such as: "decoration := WAValueHolder with: 
(WADecoration new owner: self)" or some such?
