I have a issue using BOs in a parrent-child relationchip in DevExpress GridView (My setup is described in my previous post here: http://forum.strataframe.net/Topic28318.aspx) . When I expand a parent record to show a child record it shows me lets say ChildRec1, but if I open another child (say ChildRec2), leaving the first one visible, both of the visible children change to ChildRec2. Each next child exposed will change all other children that are already open to the last one. ShareDataTableKey is empty and ShareDataTableKeyShareIndexRow is false on all BOs.
