I have a class mapping where it has a subset of the same class like this:

Code:

 <class name="com.app.beans.ContactEvents" table="ContactEventType">
       <id name="eventId" column="eventId">
          <generator class="assigned" />
       </id>
        <property name="date"         column="dateStamp"/>
        <property name="description"   column="description"/>
        <property name="eventCode"      column="eventCode"/>
        <property name="superTypeId"   column="superTypeId" />
        <property name="status"         column="status" />
        <set name="contents">
           <key column="superTypeId" />
           <one-to-many class="com.app.beans.ContactEvents"/>
        </set>
    </class>

Then, I only want to get parent ContactEvents with status='active' that will also hold a set of ContactEvents with status='active' as well.

Can I put a condition in this mapping definition itself? how?
Or how can I do it in HQL?

There are some similar mapping examples like this on the net (like the cat /kittens example), but, it doesnt mention on how to approach this kind of problem.
What if I only want to retrieve only multi-colored kittens?

Thank you in advance.
