Hi everyone. I am a little new on Wicket, and I have googling this problem a lot of time.
I have 3 or 4h try to solve this exception: java.lang.IllegalArgumentException: A child with id 'eventos' already exists But as you can see on code below, I am adding just a ListView component. I ran this code step by step and I am noting that class constructor is called twice. I don't know why, I am guess that the problem have to be with that behaviour. I am using wicket 6.7.0 on tomcat 7. Running on Windows 8. Could you help me to solve this problem? *This is the HTML code:* <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd"> <wicket:head> <link rel="stylesheet" type="text/css" href="tables.css"/> <link rel="stylesheet" type="text/css" href="correos.css"/> <link rel="stylesheet" type="text/css" href="ofertasPage.css"/> </wicket:head> <body> <wicket:extend> <div id="main"> <div id="leftside"> <div class="grupo"> Eventos <wicket:link> Nueva evento <EventoPage.html> </wicket:link> Nombre Tipo Correo Inicio de recepción Cierre de recepción Cierre de recepción Pedro Marcano Pedro Marcano 0412/342-30-58 0412/342-30-58 0412/342-30-58 <images/preview-5.png> <images/edit-9.png> <wicket:link> Nuevo evento <EventoPage.html> </wicket:link> </div> </div> </div> </wicket:extend> </body> </html> *And this is the class constructor* public EventosPage() { LoadableDetachableModel<List<Evento>> ldm = new LoadableDetachableModel<List<Evento>>() { @Override protected List<Evento> load() { return Evento.getAll(); } }; add(new ListView<Evento>("eventos", ldm) { @Override protected void populateItem(ListItem<Evento> item) { Evento ev = item.getModelObject(); CompoundPropertyModel<Evento> cpm = new CompoundPropertyModel<>(ev); item.add(new Label("nombre", cpm)); item.add(new Label("tipo.nombre", cpm)); item.add(new Label("correo", cpm)); item.add(new Label("inicioRecepcion", cpm)); item.add(new Label("finRecepcion", cpm)); item.add(new BookmarkablePageLink("ver", EventoPage.class)); item.add(new BookmarkablePageLink("editar", EventoPage.class)); } }); Thanks in advance, Roger -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/A-child-with-id-XXXX-already-exist-AND-class-constructor-called-twice-issue-tp4659200.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
