I am trying to import an object that has got <many-to-one> mapping from an XML. Following is my xml:

<CategoryName metadataid="1">
<version>16</version>
<name>Infrastructure</name>
<description>Infrastructure</description>
<displayorder>4</displayorder>
<WFP wfpId="1"/>
<skills></skills>
<CategoryName>

The maping file of the above object 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 package="wfp.domain">
<class name="CategoryName"
entity-name="wfp.domain.CategoryName"
table="category_name"
dynamic-update="true"
node="CategoryName">

<id name="metadataId" column="category_name_id" node="@metadataid">
<generator class="native"/>
</id>

<version name="version" unsaved-value="null" node="version"/>

<property name="name" type="string" not-null="true" unique="true" node="name"/>
<property name="description" type="string" not-null="true" node="description"/>
<property name="displayOrder" column="display_order" not-null="true" node="displayorder"/>

<many-to-one name="wfp" column="wfp_id" not-null="true" node="WFP/@wfpId" embed-xml="false"/>

<list name="skills" cascade="all" inverse="true" lazy="false">
<key column="category_name_id"/>
<list-index column="display_order" base="0"/>
<one-to-many class="SkillName"/>
</list>
</class>
</hibernate-mapping>

Now, when I import it using the session.replicate() method it falls over in Dom4jAccessor class in Hibenate at following method:



It generates a ClassCastException at "Element ownerElement = (Element) owner" line. I debuged it and found out that it passes the "Long" object when process the many-to-one relationship of CategoryName, to this method instead of a "DefaultElement" object.
Is there anyway way to avoid this problem? Help!

add it to JIRA with a small test case
