[ http://jira.jboss.com/jira/browse/JBCACHE-674?page=comments#action_12339742 ] Ben Wang commented on JBCACHE-674: ---------------------------------- Further thoughs on this issue. It is really difficult to implement a callback mechanism for pojo update callback. For one, I can't differentitate what is field and what is whole pojo update. So one workaround maybe just to document the usage that if the clustering node are all active (e.g., each node can do attach simultaneously), the best practice is then: cacheA.attach("1", pojo1); pojo1 = cacheA.find("1"); cacheB.attach("1", pojo2); pojo2 = cacheB.find("1"); that is, after doing attach, we will always do another find again to retrieve the latest version. If it has been updated, PojoCache will recontruct the POJO instance. If not, the operation will return right away. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
