Get owner list of a list item

I'm trying to figure out how to find out what is the owner list of a list item.

My list mapping is:

Code:

  /**
   * @return m_listItems
   * @hibernate.list
   *  lazy="true"
   *  cascade="all"
   * @hibernate.collection-key
   *  column="ListId"
   * @hibernate.collection-index
   *  column="I"
   * @hibernate.collection-one-to-many
   *  class="com.mercado.s2002.businessmng.objects.rules.RuleBO"
   */
  public List getList() {
    return m_listItems;
  }

Now, suppose I have a list item (RuleBO) persistent instance, how can I find out which list holds it? I know the DB holds the list ID but I can't find out how to request it from Hibernate.

You need to use a bidirectional mapping. Please look at the "Parent Child Relationships" chapter in the reference manual.

The documentation states:
"Please note that Hibernate does not support bidirectional one-to-many associations with an indexed collection (list, map or array) as the "many" end."

So, what is the mapping I should use?

There is a workaround with explicitly mapped index properties. Search the forum.

If you find it, tell us, I'll add it to the wiki area

It was this one I think: http://forum.hibernate.org/viewtopic.php?t=926946&highlight=bidirectional+list+index
