Hi,
I am not sure what you mean that it should probably be handled inside
the person class. By updating a person with new addresses, isn't that
the case?
As for the mapping files, first is the Person mapping
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class
name="BusinessEntities.Wellness.Person,BusinessEntities.Wellness"
table="Person" lazy="true" dynamic-insert="true" dynamic-
update="false">
<id name="Personid" column="PersonID" type="int">
<generator class="native" />
</id>
<version type="binary" generated="always" name="RecordVersion"
column="`RecordVersion`" />
<property type="int" not-null="true" name="Customerid"
column="`CustomerID`" />
<property type="AnsiString" not-null="true" length="9" name="Ssn"
column="`SSN`" />
<property type="AnsiString" not-null="true" length="30"
name="FirstName" column="`FirstName`" />
<property type="AnsiString" not-null="true" length="35"
name="LastName" column="`LastName`" />
<property type="AnsiString" length="1" name="MiddleInitial"
column="`MiddleInitial`" />
<property type="DateTime" name="DateOfBirth"
column="`DateOfBirth`" />
<bag name="PersonDemogAddresses" inverse="true" lazy="true"
cascade="all">
<key column="PersonID" />
<one-to-many
class="BusinessEntities.Wellness.PersonDemogAddress,BusinessEntities.Wellness" /
>
</bag>
</class>
</hibernate-mapping>
followed by the Address mapping
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
<class
name="BusinessEntities.Wellness.PersonDemogAddress,BusinessEntities.Wellness"
table="PersonDemogAddress" lazy="true" dynamic-insert="true" dynamic-
update="false">
<id name="PersonDemogAddressId" column="PersonDemogAddressID"
type="int">
<generator class="native" />
</id>
<version type="binary" generated="always" name="RecordVersion"
column="`RecordVersion`" />
<property type="AnsiString" not-null="true" length="1"
name="AddressTypeid" column="`AddressTypeID`" />
<property type="AnsiString" not-null="true" length="60"
name="AddressLine1" column="`AddressLine1`" />
<property type="AnsiString" length="60" name="AddressLine2"
column="`AddressLine2`" />
<property type="AnsiString" length="60" name="City"
column="`City`" />
<property type="AnsiString" length="2" name="UsStateId"
column="`USStateID`" />
<property type="AnsiString" length="5" name="UsPostalCodeId"
column="`USPostalCodeID`" />
<many-to-one name="Person" cascade="none" column="PersonID" />
</class>
</hibernate-mapping>
