[jboss-dev-forums] [Design of JBossCache] - Re: CacheListener notifications during data gravitation

Kinda hacky though.

Should node removals originating from data gravitation cleanups emit notifications in the first place?  I suppose so, for correctness and predictability of behaviour.  

What about an additional parameter to the remove notification, to indicate whether the remove is cluster-wide (i.e., a REAL remove) or local (i.e., a data gravitation cleanup)?  This would be a 2.0.0 fix though.
