_opList is a binding list of your Resource object.
_bsAppts is a binding list of my business object appointments

I am creating a hierarchy grid using object relational data.  I am adding a GridViewRelation manually to link the two classes together.  The data loads correctly at first, but then selecting a child row will cause all child rows in that position to be duplicated and selected.

After initial data load, everything looks great.

Select Child 2_1 and all first position children are selected.

(see select1.png)

Select Child 3_2 and now all second position children are selected, and the first position children are now duplicates of each other and read Child 4_1.

(see select2.png)


Here is the code:
