every page accessed logs a WicketNotSerializableException
---------------------------------------------------------
Key: GEOS-2084
URL: http://jira.codehaus.org/browse/GEOS-2084
Project: GeoServer
Issue Type: Bug
Components: Wicket UI
Reporter: Gabriel Roldán
Assignee: David Winslow
Fix For: 2.0
Accessing a page from the new UI consistently logs a
{{org.apache.wicket.util.io.SerializableChecker$WicketNotSerializableException}}
in stdout
This wasn't happening yesterday though.
Here's a sample exception report from the console:
