I'm getting a SerializationException on org.jboss.seam.core.Messages from my stateful
session bean and it's quite unclear to me why or how. I'm using Seam extended
managed persistence. (Which is relevant or irrelevant?) Can anybody explain how this is
possible?
code snippet
| @Stateful
| @Name("groupManager")
| @LoggedIn
| public class GroupManagerBean implements GroupManager, Serializable {
|
| @In(create=true)
| private EntityManager orgmobDatabase;
|
| @In(create=true)
| private Map<String, String> messages;
|
| @In(create=true)
| private transient FacesMessages facesMessages;
|
| private transient Map<Locale,MembershipComparator> membershipComparatorMap;
|
| public GroupManagerBean() {
| initMembershipComparatorMap();
| }
|
| private void initMembershipComparatorMap() {
| membershipComparatorMap = new HashMap<Locale,MembershipComparator>();
| }
|
| private void readObject( ObjectInputStream in )
| throws IOException, ClassNotFoundException {
| in.defaultReadObject();
| initMembershipComparatorMap();
| }
|
| }

I know I don't have an explicit serialVersionUID but I (naively?) didn't think
that could make a difference since all I'm doing right now is repeatedly deploying my
app to JBoss which only uses one compiler (1.5.0_07-b03, though I don't think that
matters) and undeploys any previously installed version of my app. I can show more code
if that's needed. The stack trace is:

I'm using Seam 1.0.1.GA and JBoss 4.0.4.GA from the JEMS installer. My searching for
other similar instances didn't turn didn't turn up ones like it. I hope it's
OK to post this here.
Thanks,
David
