[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3351) Dynamic entity model and inheritance - exception when trying to persist
Dynamic entity model and inheritance - exception when trying to persist
-----------------------------------------------------------------------
Key: HHH-3351
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3351
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Reporter: Adam Warski
I have two dynamic model entites mapped as follows:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class entity-name="Superclass" discriminator-value="A">
<id name="id" type="integer"><generator
class="native"/></id>
<discriminator column="DISC" type="string" />
<property name="dataA" type="string"/>
<subclass entity-name="Subclass"
discriminator-value="B">
<property name="dataB" type="string"/>
</subclass>
</class>
</hibernate-mapping>
When I try to persist one of them (just invoking session.persist("Superclass",
new HashMap()); is enough) I get the following exception:
Exception in thread "main" org.hibernate.HibernateException: instance not of
expected entity type: java.util.HashMap is not a: Superclass
