I'm not sure whether this is a bug or not, but it occupied a chunk of my time trying to debug this, and I thought others should be aware of it. The javassist proxy for javaBeans components interferes with the default equals() method. After some interceptions, something like instance_javassist.equals(instance) is called, which fails, because they're different instances. You can see this with something like this (which fails): | public class PingTest extends SeamTest { | | @Test | public void test() throws Exception { | new FacesRequest() { | @Override | protected void invokeApplication() { | //call action methods here | Ping ping = (Ping) getValue("#{ping}"); | Collection<Ping> pingSet = new ArrayList<Ping>(); | pingSet.add(ping); | assert ping.equals(ping); | } | }.run(); | } | } | | @Name("ping") | public class Ping { | | @Logger private Log log; | | @In FacesMessages facesMessages; | | public void ping() | { | log.info("ping.ping() action called"); | facesMessages.add("ping"); | } | | | } | If it's a bug, I'll file it in jira.
