Help creating a custom JSF component and adding a validator to it.

[ala alal]

Hi all,
I would like to implement my custom component. It is basically an InputText with many other features.
I created it and all is ok but I can't add a tag <f:validator> inside cause it give me the error "Not nested in a tag of proper type."
What can I do?

Html code is that:
<myf:specialInput [...] >
<f:validator validatorId="myValidator">
</myf:specialInput>

the two class files are:
public class SpecialInputTag extends UIComponentTag (also deprecated...what I have to use??) : for the tag
public class SpecialInput extends UIPanel implements NamingContainer : for the renderer and component

Help me, thanks!

It was three days I was trying it and now that I posted the problem I solved it.
OK OK OK.
If someone else have my problem the component you are creating must extends UIInput. I solved with that.
Bye.

I have a new problem. The problem appears during the rerendering of my custom component.
It keeps some children inside and during the restore it give me an ArrayIndexOutOfBoundException.
I solved with the solution posted here: LINK that I report here:

  
public class CompositeJsfComponent {
 
    public CompositeJsfComponent() {
        // MyInput extends UIComponent
        getChildren().add(new MyInput());
        getChildren().add(new MyInput());
        getChildren().add(new MyInput());
    }
 
    public Object processSaveState(FacesContext context) {
        Object superState = super.processSaveState(context);
        return new Object[] {superState, new Integer(getChildCount())};
    }
    
    public void processRestoreState(FacesContext context, Object state) {
        // At this point in time the tree has already been restored, but not before our ctor added the default children.
        // Since we saved the number of children in processSaveState, we know how many children should remain within
        // this component. We assume that the saved tree will have been restored 'behind' the children we put into it
        // from within the ctor.
        Object[] values = (Object[]) state;
        Integer savedChildCount = (Integer) values[1];
        for (int i = getChildCount() - savedChildCount.intValue(); i > 0; i--) {
            getChildren().remove(0);
        }
        super.processRestoreState(context, values[0]);
    }
 
}

Why I need to remove children from the tree? Why they are duplicated? Does anyone has a better solution?
Thanks.
