 Post subject: composite-element inside component

I have a class Document that has a component of type MetaInfo. MetaInfo itself maintains a list of entries (class MetaInfoEntry).

I get the following exception:
No persister for: org.tdr.document.MetaInfoEntry

Why do I need a persister for this class?

Here is the mapping I use:

Code:
<hibernate-mapping>
  <class name="eg.GenericDocumentData" table="document_values">

    ....

    <component name="metaInfo" class="eg.MetaInfo">

      <list name="entries" table="documents_meta_info"
            cascade="all-delete-orphan">

        <key column="document_id" />

        <index column="idx" />

        <composite-element class="eg.MetaInfoEntry">

          <property name="element" type="java.lang.String" not-null="true" />
          <property name="qualifier" type="java.lang.String" />
          <property name="value" type="java.lang.String" not-null="true" />

        </composite-element>

      </list>

    </component>

    ....

  </class>

</hibernate-mapping>

The error occurs when I try to save a newly created Document instance using saveOrUpdate().

Here's the stack trace:

OK, I've just figured out that it works when I use cascade="all" instead of cascade="all-delete-orphan".

So, what's the problem with all-delete-orphan in this case? I really would like the orphans to be deleted when I save a document.
