Entities referencing domain style Entities

[Luther Baker]

I have an entity that contains another entity - but this time, the contained
entity table is quite finite - say, 10 rows.

public class Category
{
  private String name;
}

public class User
{
   private String firstName;
   private String lastName;
   private Category category;
}

and in this case, I'd like to render firstName, lastName and a DROP DOWN or
some type of picker from existing Categories.

Would I need to create my own t:form ... and possibly use a t:BeanEditor
with a custom drop down/picker -- or is this type of idiom encapsulated in a
Tapestry component already?

Thanks much,
