Why is @Init not evaluated in parent classes?

Hi everybody,

I've got an abstract class where all my VMs inherit from. I could have an @Init annotated method in the abstract class, but ZK won't evaluate it. So I have to have this init method in every subclass:

@Init
@Override public void init()
{
    super.init();
}

I've read the docs on how to call an additional init() method in the parent class. But there seems to be no way to have the @Init method ONLY in the parent class, right? Why is that?

I'm happy to provide a patch which fixes this if there's no reason to not do it.

Cheers, Thomas

I think the ZK guys assumed that in most cases you will always need an @init method in your view model to retrieve parameters and prepare data models. Anyway, i believe that a declaration like this is not a big thing:

@Init(superclass=true)
public void init() { }

Hi Thomas. Yes, it's possible.

In your concrete viewmodel define the annotation at class level:

@Init(superclass = true)

public class ManageCitiesViewModel extends CrudViewModel<city>

Then in yout abstract class:

@Init

public void load()

It's working fine for me. If this is what you want please vote me. Regards!
