I believe I am having this same issue. I will post all my info,
hoping to help. I'm going to try Kevin's fix for now to see if it
works, and if I have time, I'll also attempt to help.
I have a Poll that has a list of Answers. If I leave it at that, it
works fine. But as soon as I add a many-to-one of an Answer has one
Poll, it gives me the error that's at the bottom of this.
If you need anymore info, let me know. Thanks in advance.
I see the problem, and it looks to be the same as Kevin's. Namely,
the mapping on answer has this: <many-to-one name="Poll" column="" />
hbm.xml:
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-
access="">
<class name="OCS.Data.Entities.BaseEntity, OCS.Data,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
table="`BaseEntity`" xmlns="urn:nhibernate-mapping-2.2">
<id name="Id" type="Int32" column="Id">
<generator class="identity" />
</id>
<joined-subclass name="OCS.Data.Entities.Poll, OCS.Data,
Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">
<key column="BaseEntityId" />
<property name="Question">

</property>
<bag name="Answers">

<one-to-many class="OCS.Data.Entities.Answer, OCS.Data,
