Hi,
I have a strange CCE on page deserialization with wicket 1.3.0-beta3:
java.lang.ClassCastException: cannot assign instance of
org.apache.wicket.model.PropertyModel to field
org.apache.wicket.markup.html.WebMarkupContainerWithAssociatedMarkup.markupHelperof
type
org.apache.wicket.markup.html.ContainerWithAssociatedMarkupHelper in
instance of org.xoocode.xooctory.web.component.form.LabelBorder

The component on which I have the problem, LabelBorder, is a very simple
Border component:
public class LabelBorder extends Border {
private static final long serialVersionUID = 1L;
public LabelBorder(String id, IModel model, String label,
String htmlTip) {
super(id, model);
add(new Label("label", label));
if (htmlTip != null) {
add(new ToolTipComponent("help", htmlTip));
} else {
add(new WebMarkupContainer("help"));
}
}
public LabelBorder(String id, String label,
String htmlTip) {
this(id, null, label, htmlTip);
}
}
So I'm wondering what can be going wrong. Any idea?
