Walking the stack I get to a message in aFactorialTableComponent >>
addDecoration: aDecoration
"Add aDecoration to the receivers decoration chain. Answer the added decoration."
	
	| previous current |
	previous := nil.
	current := self decoration.
"etc.."
I see that decoration returns nil and therefore "^ decoration contents"
generates the error condition.

contained in the following file.
