best way to obtain component reference?

[Phillip Rhodes]

I am trying to update the label text on a page from a inner class (onSubmit) of 
my page.

I used the page.get("componentid") method, but it returns null.  While I could 
just store the reference to the label as a variable in my page class, I would 
like to understand how to obtain a reference to it using the wicket API.

When I use the following snippet, my "get" method always return null.

Thanks, appreciate the help.

public class AdminPage extends WebPage {
    public AdminPage() {
        add(new Label("message", "If you see this message wicket is properly 
configured and running"));
        DMIRequest dmiRequest = new DMIRequest();
        Form myform = new Form("myform", new CompoundPropertyModel(dmiRequest));
                add(myform);
                
                myform.add(new DeleteButton());
    }
}

        private  class DeleteButton extends Button
        {
                private static final long serialVersionUID = 1L;

                private DeleteButton()
                {
                        super("delete", new ResourceModel("delete"));
                        setDefaultFormProcessing(true);
                }

                @Override
                public void onSubmit()
                {                                               
                          Label lbl = new Label("message", "Deleted");
                              this.get("message").replaceWith(lbl);
                               
                        
                        
                        
                        
                }
        }
