Hi,
If I understand you question correctly, all you need to do is define the
value of the PropertySelection component to your Class's teacher's property.
Since you didn't show any code, here is an example I made up:
<component id="teacherSelection" type="PropertySelection">
<binding name="model" expression="teachersSelectionModel"/>
<binding name="value" expression="class.teacher"/>
</component>
That's all you really have to do.
Hope this will help,
Ben
