Why isn't this common interface working?

I have a set of generic interfaces and classes

public interface IElement {
// omited
}

class Element implements IElement {
// omited
}

public interface IElementList<E extends IElement>  extends Iterable {
   public Iterator<E> iterator();
}

class ElementList implements IElementList<Element> {

    public Iterator<Element> iterator() {
       // omited
       }
}


public interface IElementListGroup<E extends IElementList<? extends IElement>> {
    public E getChosenElementList();
}


class ElementListGroup implements IElementListGroup<ElementList> {
    public ElementList getChosenElementList() {
        // omited
    }
}

      

        
        
        
      

    

And then the simple code

ElementListGroup group;

for(Element e : group.getChosenElementList())
{
 // omited
}

      

        
        
        
      

    

And the line with the throwe keyword is an error "don't convert from Object to Element".

Thanks in advance.
