I'm just beginning with GAE, and although I've programmed in Java
before, I'm a little rusty. I'm trying to create a bookmark manager
application.
I have two objects, a Category object and a Bookmark object. I want
the Category object to be able to store multiple sub-categories as
well as multiple bookmarks:
--snip--
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Category
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key CategoryId;
@Persistent
private String _Title;
@Persistent
private List<Category> _Categories;
@Persistent
private List<Bookmark> _Bookmarks;
--snip all the public methods, etc--
However, when I try to store a new category into the datastore, it
stores nothing. When I remove the List<Category> property, it stores
fine. Is there something I'm doing wrong with regards to an object
being a child of itself?
I've tried to search for this, but haven't been able to find anything.
Thanks.
Brent
