I have a common library used by many of our applications,
Common.DataObjects.dll
In this library, I have defined a NewsItem
In our new calendaring application, I've created a subclass,
CalendarNewsItem, which adds a few properties and methods to NewsItem.
This is in Common.Cal.dll
In this application, all NewsItems are CalendarNewsItems (CNI for
short).
I've got the mapping file for NewsItems in Common.DataObjects.dll and
the mapping file for CNI in Common.Cal.dll, setup like so:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Common.DataObjects" namespace="Common.DataObjects">
<class name="NewsItem" lazy="false" table="NewsItems" schema="dbo">
<id name="ID" column="NewsItemID" type="int" unsaved-value="0"
access="nosetter.lowercase-underscore">
<generator class="identity"/>
</id>
<property name="Headline" type="string" not-null="true"
length="255"/
>
<property name="Subhead" type="string" length="255"/>
<property name="Source" type="string" length="255"/>
<property name="ExternalUrl" type="string" />
<property name="ArticleText" type="string" />
<property name="ContactName" type="string" length="255" />
<property name="ContactEmail" type="string" length="255" />
<property name="ContactPhone" type="string" length="255" />
<property name="ReleaseDate" type="datetime" not-null="true" />
<property name="ExpirationDate" type="datetime" />
<!-- Enumeration properties. Always specify enum type. -->
<property name="SourceType" type="NewsItemSource" />
</class>
</hibernate-mapping>
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Common.Cal" namespace="Common.Cal">
<union-subclass name="CalendarNewsItem"
extends="Common.DataObjects.NewsItem, Common.DataObjects,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" lazy="false"
table="NewsItems" schema="dbo">
<many-to-one name="Calendar" class="Calendar"
column="CalendarID"
lazy="false" not-null="true" foreign-key="FK_NewsItems_Calendars" />
</union-subclass>
</hibernate-mapping>
When I try to run, I get this runtime exception:
These classes referenced by 'extends' were not found:
FullName:Common.DataObjects.NewsItem -
Name:Common.DataObjects.NewsItem, Common.DataObjects, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null
What am I missing here? Thanks everyone!
