Hi Jiri, have you tried to *bind* UIDataTable via <wap:dataTable binding="#{bean.table}" var="b" ... > to a backing bean?
If I have in Bean: private UIData tabelle = new UIData(); (plus it's set/get) also I call setValue() and set an Array of a clazz I developed In JSP: <wap:column> <wap:outputText value="#{b.erklaerung}"/> I logged that getErklaerung() of my custom clazz is called, but nothing gets rendered. If I use value instead of binding it works. Any ideas? Thanks! Best regards Matthias
