[infinispan-dev] Cache Store Does'nt Work Async Whenever Modification is Inside Transaction

Amin,

I've been checking the replace behaviour but I don't understand what's 
your problem exactly.

CacheStoreInterceptor deals with replace calls in exactly the same 
situation as it does for puts. If the command is successful, iow if the 
value was replaced, then it calls CacheStore.store(), which is the same 
as it'd do with cache.put().

Cheers,
