Steps to Reproduce:
- (Re)start GeoServer
- Navigate to localhost:8080/geoserver/web and login
- Navigate to the Server Status page.
- Click the System Status tab
- Click the Modules tab. This will give an error (below). The error sometimes does not occur if you have already viewed the Module tab during the current GeoServer session.
Error message:
org.apache.wicket.behavior.InvalidBehaviorIdException: Cannot find behavior with id '0' on component 'org.geoserver.web.admin.ModuleStatusPanel:tabs:panel' in page '[Page class = org.geoserver.web.admin.StatusPage, id = 4, render count = 1]'. Perhaps the behavior did not properly implement getStatelessHint() and returned 'true' to indicate that it is stateless instead of returning 'false' to indicate that it is stateful.
