PHL, I'm sorry but it's hard to understand what your are trying to do. Anyway, I find the X1 class very strange. I think you simply need to remove the "ajout" method as the label is already added in the constructor. You cannot add a label several times on the same panel unless you are using a repeater.
public class X1 extends Panel { public X1(String id, String ColumnTilte) { super(id) ; lbl = new Label("labelx", ColumnTilte) ; add(lbl) ; add(new Label("phl","added by constructor")) ; } public Label getLabel() { return lbl ; } } regards, Gabriel. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Misunderstanding-Unable-to-find-component-with-id-phl-or-A-child-with-id-phl-already-exists-tp4674083p4674087.html Sent from the Users forum mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
