Is it in some way possible to create a wizard like form or open an action with
an action? I tried to return a not yet persisted object from an action and
hoped I could edit some properties and add some elements to collections of the
object before persisting it to the database...

Dan:
Short answer is that we don't really (properly) support this. And we should.
I agree that @NotPersistable is confusing and its not clear what to use; the
right solution would be to implement a view model (currently: implement the
ViewModel interface), and then - optionally - write a custom ComponentFactory
for the Wicket viewer to render the wizard appropriately.
But the snag even with the above is that (currently) view models are immutable;
they support actions but their properties cannot be edited.
I can see the way forward on this; I don't think it's difficult, but it will
require a change in core and probably the wicket viewer also.
