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: <?xml version="1.0" encoding="UTF-8" ?> <server>    <mbean code="org.jboss.cache.pojo.jmx.PojoCacheJmxWrapper"           name="jboss.cache:service=PojoCache">       <!-- Configure the TransactionManager       <attribute name="TransactionManagerLookupClass">          org.jboss.cache.transaction.DummyTransactionManagerLookup       </attribute> -->       <attribute name="TransactionManagerLookupClass">          org.jboss.cache.transaction.JBossTransactionManagerLookup       </attribute>             <!-- Isolation level : SERIALIZABLE                              REPEATABLE_READ (default)                              READ_COMMITTED                              READ_UNCOMMITTED                              NONE       -->       <attribute name="IsolationLevel">REPEATABLE_READ</attribute>       <!-- Valid modes are LOCAL, REPL_ASYNC and REPL_SYNC -->       <attribute name="CacheMode">REPL_SYNC</attribute>               <!--  Specific eviction policy configurations.
