this doesn't happen all the time.  i did see this.  and have lots of evidence ...client-side and server-side call stacks, screenshots.  someone in dev should look at this more closely as there were recent changes that may have manifested this.

Mike, the root case of this issue appears to be the following error in your Server log:

2011-11-08 10:40:13,042 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/coregui]] org.rhq.enterprise.gui.coregui.CoreGUI ResourceTypeGWTService: ERROR: The serialization policy file '/org.rhq.enterprise.gui.coregui.CoreGUI/8FCB27A596CBB66256CC18F554A1C6F4.gwt.rpc' was not found; did you forget to include it in this deployment?
2011-11-08 10:40:13,043 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/coregui]] org.rhq.enterprise.gui.coregui.CoreGUI ResourceTypeGWTService: WARNING: Failed to get the SerializationPolicy '8FCB27A596CBB66256CC18F554A1C6F4' for module ''; a legacy, 1.3.3 compatible, serialization policy will be used.  You may experience SerializationExceptions as a result.

I have never seen this error myself, so I'm thinking it's something in your environment. This post suggest that the error can occur when the GWT app is behind a reverse proxy:


Is that true for you by any chance?

The URL it fails to load is, which is an internal (dynamic?) address. Is it possible your VPN or Internet went down when the error occurred, or that your internal IP address had changed to something other than I typically access my Server using, rather than an external IP address, which may be why I've never encountered this. Tomorrow I'll try using an external address throughout the day to see if I encounter the error.

This seems environmental.  I recommend closing.
Comment 6 Jay Shaughnessy 2012-08-20 14:15:36 EDT
Setting back to NEW since the assignment is invalid. Also, I think it can be closed.
