[jboss-jira] [JBoss JIRA] Reopened: (JBAS-3463) Loading of persisted XMBean attributes does not work for custom types

Loading of persisted XMBean attributes does not work for custom types --------------------------------------------------------------------- Key: JBAS-3463 URL: http://jira.jboss.com/jira/browse/JBAS-3463 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: JMX Affects Versions: JBossAS-3.2.8.SP1, JBossAS-4.0.4.GA Reporter: Dimitris Andreadis Assigned To: Dimitris Andreadis Fix For: JBossAS-3.2.8.SP2, JBossAS-4.0.5.GA, JBossAS-5.0.0.Beta3 When using XMBean persistence for a complex attribute (my own type), all seems to go well when changes are persisted/serialized, but when the XMBean is redeployed (and its persisted state is read), there are problems unserializing the serialized data
