Hi,
How could I add Restrictions to the createCriteria using composite-id key ?
The program works fine with session.createCriteria(Calendar.class).list();
but i do not know how to restrict it by a key-property name="courseId".
The composite-id class is CalendarId.
Here are my codes:

CalendarId idCalendar=new CalendarId(courseId);

list= session.createCriteria(Calendar.class).list();


defined the calendar table with two classes
Calendar.class and CalendarId.class(for Composite id)

and the calendar.hbm.xml :
<hibernate-mapping>
<class name="entity.Calendar" table="calendar" catalog="cwsei_hibernate">
<composite-id name="id" class="entity.CalendarId">
<key-property name="id" type="int">
<column name="Id" />
</key-property>
<key-property name="courseId" type="int">
<column name="courseId" />
</key-property>
<key-property name="year" type="string">
<column name="year" length="4" />
</key-property>
</composite-id>
<property name="title" type="string">
<column name="title" />
</property>
..........

<property name="title" type="string">
<column name="title" />
</property>
</class>
</hibernate-mapping>
Thanks,
MK
