> Erik Hair on users@i.a.o:
> 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.
