Hello,
I have two mapping files defined as:
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FirstSample"
namespace="FirstSample.Domain" xmlns="urn:nhibernate-mapping-2.2">
<class name="RptSourceGroup" table="RPT_SOURCE_GROUP" lazy="true" >
<!--
<id name="GroupId" column="GROUP_ID" />
<id name="GroupId" type="Int64" column="GROUP_ID">
<generator class="assigned" />
</id>
-->
<id name="GroupId" type="Int64" column="GROUP_ID">
<generator class="sequence">
<param name="sequence">RPT_SOURCE_GROUP_SEQ</param>
</generator>
</id>
<property name="Name" column="NAME" />
<property name="Country" column="COUNTRY" />
<property name="Year" column="YEAR" />
<property name="Asset" column="ASSET" />
<property name="Frn" column="FRN" />
<property name="MediaType" column="MEDIA_TYPE" />
<property name="Annotation" column="ANNOTATION" />
<property name="Status" column="STATUS" />
<property name="Created" column="CREATED" />
</class>
</hibernate-mapping>
and
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="FirstSample"
namespace="FirstSample.Domain" xmlns="urn:nhibernate-mapping-2.2">
<class name="RptSource" table="RPT_SOURCE" lazy="true" >
<id name="SourceId" type="Int64" column="SOURCE_ID">
<generator class="sequence">
<param name="sequence">RPT_SOURCE_SEQ</param>
</generator>
</id>
<many-to-one name="RptSourceGroup" column="GROUP_ID" />
<property name="Name" column="NAME" />
<property name="Body" column="BODY" />
<property name="SourcePath" column="SOURCE_PATH" />
</class>
</hibernate-mapping>
They share the same namespace but have different class names. In the
code where I am configuring my session (NHibernateHelper class), I
have the following:
var configuration = new Configuration();
configuration.Configure();
configuration.AddAssembly(typeof (RptSourceGroup).Assembly);
configuration.AddAssembly(typeof (RptSource).Assembly);
When I run my app the following error is thrown during the second
AddAssembly call:
ERROR: NHibernate.MappingException: Could not compile the mapping

Any clues as to why this is happening?
Thanks - Peter
