Any object stored in a model must be serializable and your object
com.tvh.website.application.external.ApplicationPage$ExternalApplicationBean
is not.
You can either make it serializable or use a model that finds your
ExternalApplicationBean when it loads e.g. LoadableDetachableModel. You can
even nest this model inside a CompoundPropertyModel like
This would be the way to go:)
new CompoundPropertyModel(new
MyBeanFindingLoadableDetachableModel(myBeansId)))
Or you could just extend the LoadableDetachableModel where you use it
and implement the load method...

The issue is due to how wicket saves pages to disc in order to support the
back button.

Hello,
I'm using a rather complex CompoundPropertyModel on my Form. That Form
contains multiple Panels that also use the same CompoundPropertyModel. So
I can't post any source code, but I hope my stacktrace will be enough.
I also found a rather simular problem on the jira site, but not for wicket
but MyFaces.
http://issues.apache.org/jira/browse/TRINIDAD-27
Should I post this on the jira for wicket or am I doing something wrong?
Thanks !
