This ought to work, but I haven't tested it:
(ea isDecoration and: [ea isDelegation]) ifTrue:
[self removeDecoration: ea]]

Need to access it from where? One interesting property of 2.5 is that
in either a render method or in a callback, the dynamic context is
equivalent to the UI nesting - which means that if you walk back up the
stack, you're also walking up the (current, dynamic) parent component
chain. This is probably the best way to find the root.
Otherwise, yeah, just stick it in an inst var on Session, I'd say...
