Hello All,

I've just upgraded to 2.8 (on a fresh squeak image) and after importing 
an existing 2.7 application, I am receiving and error in the decoration 
chain:

==
MessageNotUnderstood: UndefinedObject>>contents

Stack Trace
    1.
       thisContext
           UndefinedObject(Object)>>doesNotUnderstand: #contents
       self
           nil
       aMessage
           contents
    2.
       thisContext
           FVIndex(WAComponent)>>decoration
       self
           a FVIndex
    3.
       thisContext
           FVIndex(WAComponent)>>decorationChainDo:
       self
           a FVIndex
       aBlock
           [] in FVEntryPoint(WAPresenter)>>withNextPresentersDo: {[:ea 
| ea withNextPresentersDo: aBlock]}
==

I've followed Philippe's guide on 
http://article.gmane.org/gmane.comp.lang.smalltalk.squeak.seaside/10692/

IS there something else I am missing?
Newly created applications do not cause this issue, if that helps.

Many thanks,
John.
