If you want to remove an object from a scope
You can put this in an @Observer method, and raise an event when you modify the user list (this is a very neat way of doing what you are after IMO).
Thanks Pete, I'll give that a go.
Oh, I should have asked.
I assume "foo" refers to the Seam component name? Is there a way to get this without typing it in directly (i.e. "this.getContextName()" or some such thing)
Yes and no.
