DataView listen to Datagrid 2

How do we get a DataView to listen to a Datagrid 2? It simply doesn't list the DataGrid 2 in the dropdown [Edit] This is my setup: Domain Model Page Setup:   I have a datagrid of Category (named "GridCategory”) . Next to it is a DataView which listens to GridCategory. In this DataView i have placed a datagrid of CIGroup and defined an XPath constraint which lists all the CIGroup objects of "GridCategory”. This works fine for the datagrid . Now when i upgraded to Studio Pro 9 and replaced the new widget "Datagrid 2” for Category it simply doesn't list the new grid in the dropdown of grids like above
