According to the documentation on
http://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html#Keys
it should be possible to retrieve an entity using a different key type
than the key field in the class.
Assuming the following entity having a key (encoded string) and a
keyId like
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String encodedKey;
@Persistent
@Extension(vendorName="datanucleus", key="gae.pk-id",
value="true")
private Long keyId;
it should be possible to retrieve the entity by both
pm.getObjectById(myEntity.class, encodedKey);
and
pm.getObjectById(myEntity.class, keyId);
do I understand that correctly? - (since it does not work out for my
code)
thanks,
andr
