If you are going to store a Master-Entry with Detail-Entries by saving the context I got this error:
Innere Ausnahme 1:
OracleException: ORA-02291: Integritäts-Constraint (HR.FK_OrderDetails_Orders_OrderID) verletzt - übergeordneter Schlüssel nicht gefunden
ORA-06512: in Zeile 13
I suppose, that the Detail-Entry is stored before the Master-Entry is. With EF6 same code works fine.
