    Remote node did not update when modifying a node

    Oliver Yang Newbie

      Hi, every one

       

      I have two jboss instances with a pojocache each are running in different server and share one database, I cluster the cache in a group. The cache mode is REPL_SYNC and my cache loader is JDBC cache loader.When I attach a node and detach a cache, they both work fine, when I use following codes to modify a cache, only local cache is modified and remote cache still remain same.

           MyObject obj = (MyObject)pojoCache.find("theKey");

           obj.setValue("newValue");

           //that all

      If I should use attach() to attach the modified object again, the remote cache will be changed. Can any one knows the issue?

       

      I have a cache listener added to the cache to debug all events, but FieldModifiedEvent event never happened. my cached configuration is:
