Hi, thanks Ferrari
Yes, many times, simply does not work, the list "DocSct.DocScStList" still empty, just when do "DocSct.DocScStList.count" an extra query is executed (but this is not the issue), then i need to do eagerload DocSct.DocScStList.DocSett one by one, with the for cicle.
Correction:
Result := Manager.Find<TDocSct>.Add(TLinq.Eq(Dic.DocSct.Id.PropName, Id)) .UniqueResult;
...
Thanks again
