Hi!
I get the error message in the title.
I have two classes (Geo.cs and Coordinates.cs). They have a one-to-one relationship.
Geo.cs:
Code:
private int id;
private string city;
private string accessory;
private Coordinates coordinates;
private int areaCode;
private string federalState;
getters, setters and constructor...
Coordinates.cs
Code:
private int plc;
private double longitude;
private double latitude;
getters, setters and constructor...
I'd like to have a unique Plc in Coordinates.cs. It's primary key and also foreign key.
My Mapping files:
Code:
<class name="Geo" table="geo_table">
<id name="Id" column="id" type="Int32">
<generator class="native"/>
</id>
<property name="City" column="city" length="40" not-null="true"/>
<property name="Accessory" column ="accessory" length="40" not-null="false"/>
<property name="AreaCode" column="area_code" length="8" not-null="false"/>
<property name="FederalState" column="federal_state" length="30" not-null="true"/>
<one-to-one name="Coordinates" class="Coordinates" cascade="all"/>
</class>
AND
<class name="Coordinates" table="plc_coordinates_table">
<id name="Plc" column="plc" type="Int32" length="5">
<generator class="foreign">
<param name ="property">Plc</param>
</generator>
</id>
<property name="Longitude" column="longitude"/>
<property name="Latitude" column="latitude"/>
</class>
I tried also Coordinates instead of Plc as param name. But that doesn't work too.
Do you have any idea??
Regards, Joe
