I get this exception when testing modal window with a page
(wicket-examples/ajax):
wicket.util.io.WicketSerializeableException: Error reading field:
locale for object class: class
wicket.markup.html.image.resource.LocalizedImageResource$1
children->children->children->children->localizedImageResource->resourceReference
NOTE: if you feel Wicket is at fault with this exception, please
report to the mailing list. You can switch to JDK based serialization
by calling: wicket.util.lang.Objects.setObjectStreamFactory(new
IObjectStreamFactory.DefaultObjectStreamFactory()) e.g. in the init
method of your application

Johan, could you take a look?
I'm also wondering why the modal window has to read from the history
to start with... (though I admit I haven't looked into it at this
point).
