nhibernate - table per type inheritance error

[shahary]

Hello,

I am trying to import hbm.xml file into the Devart Nhibernate Model (via visual studio).
The file contains the following definitions:
<class name="Party"
abstract="true"
table="Parties">
<id name="Id">
<generator class="identity"/>
</id>

<joined-subclass
table="People"
name="Person">
<key column="PartyId"/>
<property name="FirstName"/>
</joined-subclass>

<joined-subclass
table="Companies"
name="Company">
<key column="PartyId"/>
<property name="CompanyName"/>
</joined-subclass>
</class>

When the process ends, i get the following error:
Abstract class 'Party' cannot participate in a Table Per Type inheritance.
What is the problem with my file? It is a valid Nhibernate definition..

We will investigate this behaviour and inform you about the results as soon as possible.
As a workaround, please set Abstract property to False for the entity class Party (select Properties from its shortcut menu).

Hello MariiaI,

The code i posted here was just a little example, i am actually trying to import a very big project to Entity Developer and can't really change the base classes to be non abstract.

I am looking forward for the results of your investigation..

Thanks a lot
