^^^^^---------- this is bad. now your anonymous link component is
holding onto a detached category object, so if in categorypage's
constructor you try to access a lazy collection you will get an
exception. the proper thing to do here is to:
final Category category = (Category) item.getModelObject();
final IModel cat=new HibernateEntityModel(category);
item.add(new Link("link", cat){ setResponsePage(new CategoryPage(getModel()); }
the idea is to pass a lookup(a model) rather then the entity itself.
this way you are never holding onto the entity outside of a hibernate
session.
