Hi, we are getting closer!
We added a strategy the uuid field
@Persistent
@Strategy("com.datastax.hectorjpa.strategy.NoOpHandler")
private UUID id;
So now it successfully enhances the class which now looks like this
@javax.persistence.metamodel.StaticMetamodel
(value=com.spidertracks.aviator.model.user.Phone.class)
@javax.annotation.Generated
(value="org.apache.openjpa.persistence.meta.AnnotationProcessor6",date="Wed
Jul 13 13:00:16 NZST 2011")
public class Phone_ {
public static volatile SingularAttribute<Phone,String> countryIdd;
public static volatile SingularAttribute<Phone,UUID> id;
public static volatile SingularAttribute<Phone,String> iddCountryCode;
public static volatile SingularAttribute<Phone,String> number;
public static volatile SingularAttribute<Phone,PhoneType> type;
}
But when we go to load something it gets the list of fields, which includes
the id field, but this field is then stripped out when he meta data is
resolved.
This happens on line 164 of the ClassMetaData class in the resolveMeta
method and I get the following warning.
2011-07-13 03:16:23,295Z WARN [main] Field "
com.spidertracks.aviator.model.user.Phone.id" is not a type that is
persistent by default. If you want this field to be persistent, you have to
explicitly set it to persistent in your metadata.
Thanks
