I have this piece of code :

```
public class Profile extends Container{
    public Profile(String value) {
        Container profilo_1 =new Container();
        Container profilo_2 =new Container();

        // (1) THIS ADD A BUTTON TO THE MAIN CLASS
        this.createButton().setLabel("Modifica Profilo");

        // (2) NOW I NEED TO ADD A BUTTON INTO THE INSTANCE OF profilo_2 BUT IT FAILS
        profilo_2.add(this.createButton());

        this.add(profilo_1);
        this.add(profilo_2);        
    }
}

```

the point (2) fails, because it said that im about to adding a child to this container, but it is owner already by a container...

In fact, if i do this :

```
ILabel label=new ILabel();
profilo_2.add(label);

```

it said to me that ILabel() is abract and cannot be instantiated!

How can I fix it? Cheers to everybody :)
