Okay tried moving the @Inject from the setter to the field
declaration, still not working. Tried to add the keyword transient to
the field, still not working :/ Im a little lost here for once..
Remember it's only when my loadable detachable models are called the
2nd time, on first load it works.. The injector part of the ldms look
like this, and im on wicket 1.4.9:
import org.apache.wicket.injection.web.InjectorHolder;
import com.google.inject.Inject;
import com.netdesign.codan.dao.PhoneDao;
public class ClassWithDao {
public ClassWithDao() {
InjectorHolder.getInjector().inject(this);
}
@Inject
private transient PhoneDao phoneDao;
public PhoneDao getPhoneDao() {
return phoneDao;
}
public void setPhoneDao(PhoneDao phoneDao) {
this.phoneDao = phoneDao;
}
}
