I'm playing around with Hibernate and AndroMDA and while it generally works like a charm, it started throwing NullPointerException after me a few compile runs back:

Code:

Exception in thread "main"




and the mapping file is (IMHO it's correct):

Code:
<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 1.1//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-1.1.dtd">

<hibernate-mapping>
    <class
        name="com.triligon.addressbook.Category"
        table="CATEGORY"
    >

        <id
            name="categoryID"
            column="CATEGORY_I_D"
            type="java.lang.String"
        >
            <generator class="uuid.hex">
            </generator>
        </id>

        <discriminator
            column="class"
            type="string"
        />

        <property
            name="name"
            type="java.lang.String"
        >
            <column
                name="NAME"
                sql-type="VARCHAR(255)"
            />
        </property>

        <set
            role="people"
            table="CATEGORIES_CATEGORY_I_D_PEOPLE_PERSON_I_D"
            lazy="true"
            readonly="false"
            cascade="none"
            sort="unsorted"
        >

              <key
                  column="CATEGORIES_CATEGORY_I_D"
              />

              <many-to-many
                  class="com.triligon.addressbook.Person"
                  column="PEOPLE_PERSON_I_D"
                  outer-join="auto"
              />

        </set>

        <!--
            To add non XDoclet property mappings, create a file named
                hibernate-properties-Category.xml
            containing the additional properties and place it in your merge dir.
        -->
        <subclass
            name="com.triligon.addressbook.CategoryImpl"
            discriminator-value="CategoryImpl"
        >

        </subclass>

    </class>

</hibernate-mapping>


To make things even weirder, it will parse the first mapping file correctly but whichever comes next will fail (i.e. if I delete this mapping and let it go straight to the next that one will fail but work if it's all alone). I'm using addDirectory() to let hibernate pick up the mappings automatically.

Actually, it seems to fail on the mapping if it is the only one, as well, so it's reproduceable at least.

as if I delete the relations and regenerate my code, it works. So it's not a hibernate problem I think.
