Both Biz obj A and B are same form and the property on A is pointing to B, Biz Obj A is also the Biz obj in a Bus Binding source that is the data source for a Data Entry Grid.

Biz object A raises and handles a value changed event for one of the fields in the grid. In the handled code it does some calculation and then try's to update some values on biz obj B. 

It appears the BBS is creating a new instance of biz obj A so that when Biz Obj A handles the value changed event it is actually being handled by a new instance of A that the Bus binding source creates and thus doesnt "know" about B.

I have just started trying to think of the best way to handle this.. any ideas?

Thanks
