Re: [infinispan-dev] [ISPN-548] Discussion on updating the QueryInterceptor to be able to update old keys

Sorry, just saw this. To confirm, this should work even beyond the scope of a single
invocation, and even a single transaction, correct? E.g.,:
Tx1:
1) creates a NEW entry using cache.put()
2) new entry is indexed
Tx2 (potentially at a later date):
1) updates the entry using cache.put()
2) the index should be updated
So to that end, just checking the presence of the entry in the invocation context is not
good enough - all it will tell you is whether the entry was touched within the same scope
(whether that scope is an invocation or a transaction is irrelevant).
Mircea's solution of testing entry.isCreated() is a valid one.
Cheers
