I'm not using group forms so I can't say if it's wrong or right.
But I have a question. Does the ISublocation adapter not
dispatch the modified event to the containers items?
Are you sure that you use the ISublocation adapter which
will dispatch events to container items?
If this will not help, I think it's not bad to
implement such an event notification. Probably
in a method or with a marker which allows others
to simply disable the additional event notification.
