[Hibernate-devel] Bug with discriminator-value?

[Mark W. <mor...@SM...>]

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,
