An association from the table TransportPackages refers to an unmapped class Destination..
the map file of TransportPackage class..
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0" namespace ="IVATBusinessLayer" assembly ="IVATBusinessLayer">
<class name="TransportPackage" table="TransportPackages">
<id name="m_TransportPackageID" column ="TransportPackageID" access ="field">
<generator class ="identity"></generator>
</id>

<property name="TransportPackageName" />
<many-to-one name="m_Destination" access ="field" class="Destination" column ="TransportPackageLocationID"/>


<property name="TransportPackageNoOfDays"/>
<!--<many-to-one name ="Category" column ="TransportPackageCategoryID"/>-->
<property name="TransportPackageDescription" column ="TransportPackageDescription"/>

Do you have a mapping for Destination? Is it included as an embedded resource?
