Not sure why the presense of the overrideMe() method would change things.
When Tapestry instantiates a bean (such as a User, here) it always
finds the constructor with the *most* parameters. Here it is trying
to instantiate a User instance by injecting a User instance (into your
copy-constructor).
This has come up in other contexts. What's needed in an annotation to
tell Tapestry which constructor to use, when it has a choice.
In any case, you can handle this by contributing a
ApplicationStateContribution for type User to the
ApplicationStateManager service.
This contribution defines the strategy and creator for an Application
State Object. The only built in strategy is named "session", and the
ApplicationStateCreator interface has a single method: create().
Thus:
public void
contributeApplicationStateManager(MappedConfiguration<Class,ApplicationStateContribution>
configuration)
{
ApplicationStateCreator creator = new ApplicatonStateCreator() {
public Object create() { return new User(); } };
configuration.add(User.class, new
ApplicationStateContribution("session", creator));
}
