Hello,
since recently, once in a while I get these Exceptions, which leave me a bit
puzzled. A touch to web.config 'fixes' this for the hour, but it reappears
infrequently. This leaves me a bit weary.
I suspect my Session handling, but before I attack this, I would like to ask
for your opinion on this, maybe it is something basic I am overlooking, and
it is really just the mapping that is somehow broken...
There is only one such mapping.

The mapping:
<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" default-lazy="false"
assembly="SomeNamespace.Businesslayer"
namespace="SomeNamespace.Businesslayer">
<class name="Administrator" table="[Administrator]"
xmlns="urn:nhibernate-mapping-2.2" lazy="true">
<id name="Id" column="AdministratorID" type="Int32" unsaved-value="0">
<generator class="identity" />
</id>
<many-to-one access="field.camelcase" not-null="true"
foreign-key="FK_Administrator_Account" fetch="join" cascade="all"
unique="true" name="Account" column="AccountID" />
</class>
</hibernate-mapping>
Ideas?
