Migration from 1.5.8 to 6.1

[Marco Di Sabatino Di Diodoro]

Hi all,  

How can i convert this code into wicket 6.1. 

   item.add(new AjaxDecoratedCheckbox("toRemove", new 
Model<Boolean>(Boolean.FALSE)) {

     @Override
     protected void onUpdate(final AjaxRequestTarget target) {
        entityTO.getDerivedAttributes().remove(attributeTO);
        target.add(attributesContainer);
        }

     @Override
      protected IAjaxCallDecorator getAjaxCallDecorator() {
        return new AjaxPreprocessingCallDecorator(super.getAjaxCallDecorator()) 
{

     @Override
     public CharSequence preDecorateScript(final CharSequence script) {
         return "if (confirm('" + getString("confirmDelete") + "'))" + "{" + 
script + "} "
         + "else {this.checked = false;}";
                }
            };
         }
 });

I see the migration doc, but i not found a solution.

Thanks
M
