Errai not recovering after detecting session expiration

[dmalec]

We're seeing an issue in our app where we lose the ability to send messages from the server to the client.  It appears that Errai is attempting to handle session expiration, but getting held up during voting and never finishing bringing up the bus.  We're seeing the following in Firebug under FF15 (the problem occurs most frequently on FF, but has also been seen in Chrome and IE):

[errai] wait for: org.jboss.errai.marshalling.client.api.MarshallerFramework

[errai] vote For: org.jboss.errai.marshalling.client.api.MarshallerFramework

Is anyone else seeing this problem?

Does this happen after the app has been running for a while. Or right during initial load?

[dmalec]

The snippet above is from the initial load, where we see this happening frequently.  The other place we see this happen is during logout (the app explicitly invalidates the session on logout); in that case, we understand why Errai is reporting the session as expired, but still not sure why it gets hung up during the recovery phase.

This is now fixed: https://issues.jboss.org/browse/ERRAI-409

Thanks for the quick response!   I've built Errai from source and retested our app; the logs now show Errai recovering from the initial session expiration and completing the initialization.  Unfortunately, we're still not seeing messages pass through the bus after the recovery.  I'm not seeing any suspicious log messages in firefox, I'll see if I can find anything else suspicious.
