DefaultNestedTree Folder label

[Pascal Heus <pa...@gmail.com>]

I have a  DefaultNestedTree<CatalogItemType> tree. The CatalogItemType
is actually an Apache XmlBeans object that contains XML. By default, the
tree node labels then show the XML contant as this is I assumed what is
return by toString() method on the object.
What do I need to change/extend to get control of the Folder object
displayed label?  Is there a method I need to override in the underlying
model?
Also tried to use a NestedTree but same issue (how do I change the
Folder label?)
thanks

Create your specialized content component:

     public class CatalogFolder extends Folder<CatalogFolder> {
             ...

             protected IModel<?> newLabelModel(IModel<CatalogFolder> model)
             {
                 return new PropertyModel<String>(model, "displayProperty");
             }
     }

... and return it in your overridden AbstractTree#newContentComponent():

     @Override
     protected Component newContentComponent(String id, 
IModel<CatalogItemType > node)
     {
         return new CatalogFolder(id, this, node);
     }
