[Seaside-dev] Issue with #removeDecoration:

[John Thornborrow]

We've not overridden anything outside of the normal #updateRoot:, 
#initialize, etc.

I had suspicions that using the back button was related, but we have had 
instances where the back button was not used.

I'm still trying to pinpoint what causes it - we have some components 
that render other components and send #onAnswer: to those components. We 
also have tasks calling components that call (and sometimes #render:) 
other tasks.

Basically, I haven't narrowed it down enough yet, though I suspect it's 
only an issue during the #call: process (and possibly with the 
continuation) and not with the #answer: or #removeDecoration: process, 
as that is only a symptom.

I'll post more info when I get it.

Thanks,
John
