See my code (but nothing appears in my JSP page):
public void setPanelTabuladores(UIPanel panelTabuladores)
{
if (this.panelTabuladores == null)
{
this.panelTabuladores = panelTabuladores;

.createComponent(HtmlPanelTab.COMPONENT_TYPE);
tab0.setId("panelTab0");
tab0.getAttributes().put("label", "Variable0");

.createComponent(HtmlDataTable.COMPONENT_TYPE);
tabla0.setId("tablaEdicionPuntuaciones0");
tabla0.setVar("puntuacion0");

Well,
for very easy situations, it is ok to create it in the getter, when it
is sure that your component will not change during the life-time of a
view.
For all other things, it is much better to provide a setter and
initialize the component somewhere else so that you can dynamically
change the component and what it binds to.
regards,
Martin
