Hello, and first off thanks for your time to look at this.
For a research project I'm working on, I have a somewhat complex design (which I've been given) to persist to a database via NHibernate.
Here'
s an example of the class hierarchy:
TransitStrategy, TransportationCompany and TransportationLocation are all abstract classes.
The XML configuration I have is presently:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Vacationizer"
namespace="Vacationizer.Domain.Transit">
<class name="TransitStrategy">
<id name="TransitStrategyId">
<generator class="guid" />
</id>
<property name="Restrictions" />
<joined-subclass name="Flight" table="Flight_TransitStrategy">
<key column="TransitStrategyId" />
<property name="DepartingAirport" />
<property name="ArrivingAirport" />
<property name="Airline" />
<property name="FlightNumber" />
<property name="FlightArrivalTime" />
<property name="FlightDepartureTime" />
</joined-subclass>
<joined-subclass name="RentalCar" table="RentalCar_TransitStrategy">
<key column="TransitStrategyId" />
<property name="RentalCarBranch" />
<property name="CarMake" />
<property name="CarModel" />
<property name="CarYear" />
<property name="CarColor" />
<property name="RentalBegins" />
<property name="RentalEnds" />
</joined-subclass>
</class>
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Vacationizer"
namespace="Vacationizer.Domain.Transit">
<class name="TransportationCompany">
<id name="TransportationCompanyId">
<generator class="guid" />
</id>
<property name="Name" />
<property name="Reviews" />
<property name="Website" />
<property name="Photo" />
<joined-subclass name="Airline" table="Airline_TransportationCompany">
<key column="TransportationLocationId" />
</joined-subclass>
<joined-subclass name="RentalCarAgency" table="RentalCarAgency_TransportationCompany">
<key column="TransportationLocationId" />
</joined-subclass>
</class>
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Vacationizer"
namespace="Vacationizer.Domain.Transit">
<class name="TransportationLocation">
<id name="TransportationLocationId">
<generator class="guid" />
</id>
<property name="Name" />
<property name="Image" />
<property name="Geolocation" />
<property name="Reviews" />
<!-- <property name="HoursOpen" />-->
<property name="PhoneNumber" />
<property name="FaxNumber" />
<joined-subclass name="Airport" table="Airport_TransportationLocation">
<key column="TransportationLocationId" />
<property name="AirportCode" />
<property name="Website" />
</joined-subclass>
<joined-subclass name="RentalCarBranch" table="RentalCarBranch_TransportationLocation">
<key column="TransitStrategyId" />
<property name="Agency" />
</joined-subclass>
</class>
However, whenever I try to use this schema I get this error/stack trace:
------ Test started: Assembly: Vacationizer.Tests.dll ------

Any ideas on how I can implement this differently? Thanks very much!
