Hello!
I ran over this problem. I was retrieving a data set ordered by
encodekey ascending:
[(key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYm0gMCxIJRGJDb250YWN0GJxIDA
name EUROTRIM)
, (key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA
name ANCA ELECTRIC SYSTEMS)
, (key agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA
name TWIN TRADING)
...............
So "agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA" <
"agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA"
But
"agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYnUgMCxIJRGJDb250YWN0GJ5IDA".compareTo
("agljb3NpbnV4NjhyIQsSCkRiQ3VzdG9tZXIYn0gMCxIJRGJDb250YWN0GKBIDA") =
37 > 0
The encodedKey is defined as:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class DbContact extends DbEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String encodedKey;
@Persistent
private DbCustomer customer;
.......
Also:
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class DbCustomer extends DbEntity {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String encodedKey;
@Persistent(mappedBy = "customer")
@Order(extensions = @Extension(vendorName="datanucleus",
key="list-
ordering", value="customerProfile desc"))
private List<DbContact> contacts;
