Thx, a lot!
But after changing server/AvailabilityLocator.java to:
import com.google.web.bindery.requestfactory.shared.Locator;
import dp.verp.model.Availability;
public class AvailabilityLocator extends Locator<Availability, Integer> {
@Override
public Availability create(Class<? extends Availability> aClass) {
return new Availability();
}
@Override
public Availability find(Class<? extends Availability> aClass, Integer
id) {
return new Availability();
}
@Override
public Class<Availability> getDomainType() {
return Availability.class;
}
@Override
public Integer getId(Availability availability) {
return availability.getId();
}
@Override
public Class<Integer> getIdType() {
return Integer.class;
}
@Override
public Object getVersion(Availability availability) {
return availability;
}
}
