after setting selection, not just selected ones

When I use
obj.setSelectionProperty("multiple",true);
obj.setSelectionProperty("values",[1,2]);

only the rows listed for values (1,2) are showing in the grid. Is there a way to have all rows available in the grid, and the rows listed highlighted as selected?

Still using 1.0 until after our webapp deployment in 2 weeks.

thanks,
Debby

Maybe this is something else in your code - if I add those two lines to basic.htm - I still have all 20 rows visible and rows 2,3 selected.
