Hi,
Trying to create ShoppingList child objects with parent set to
Shopper. Persisting Shopper works fine, but when I have created a
ShoppingList and tries to persist it I get the following exception:
javax.jdo.JDOFatalUserException: Attempt was made to set parent to
me.test...@gmail.com but this cannot be converted into a Key.
Well, email works fine as key in Shopper. Why won't it play nice with
extension gae.parent-pk? Anyone?
++ Code snippet
@PersistenceCapable(identityType = IdentityType.APPLICATION)
Shopper
{
@PrimaryKey
private String email;
...
public Shopper(String email)
{
this.email = email;
}
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
ShoppingList
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
@Extension(vendorName = "datanucleus", key = "gae.parent-pk", value
= "true")
private String shopperEmail;
...
public ShoppingList(Shopper shopper)
{
shopperEmail = shopper.getEmail();
}
}
++ End of code snippet
