Hi, I have the same problem with following code:
public static RService getOneService(String owner, String idService,
PersistenceManager pm)
{
List<RService> Services = new ArrayList<RService>();
Query query = pm.newQuery(RService.class);
query.setFilter("id==keyService && idOwner==keyOwner ");
query.declareParameters("String keyService,String keyOwner ");
query.setRange(0,1);
Services = (List<RService>) query.execute(idService,owner);
Iterator<RService> iterator = Services.iterator();
if ( iterator.hasNext() ) return iterator.next();
else return null;
}
running that method cause me:
java.lang.IllegalArgumentException: __key__ filter value must be a Key

.....
id is an encoded string key, I am not using Key fields. I have other
simillar-designed classes and they are working fine with the same
query. Also above code was working as well two weeks ago....
Any ideas / solution mates?
