I seem to be having a problem with the <discriminator> element. It
works when the discriminator's type is "string," but not when it is
"integer." My mapping file looks like this:
<class name="Foo" table="Foo">
<id name="accessionId" column="fooId">
<generator class="assigned" />
</id>
<discriminator column="fooType" type="integer" />
<subclass name="FooA" discriminator-value="1">
<property name="a" />
</subclass>
<subclass name="FooB" discriminator-value="2">
<property name="b" />
</subclass>
<subclass name="FooC" discriminator-value="3">
<property name="c" />
</subclass>
</class>
And I'm getting the following error:

When I change the discriminator type to a string, however, this will
work perfectly fine... This is with the latest CVS build. Anyone else
seeing this?
Thanks,
