[flexcoders] context menu in a datagrid in flex 4

[Nitin Gopi]

Hi
I am trying to set the context menu to a datagrid. The process I am using is 
like this


cm = new ContextMenu;
cm.hideBuiltInItems();
var cmi:ContextMenuItem = new ContextMenuItem('say hello');
cm.customItems.push(cmi);

Inside datagrid I am using contextMenu="{cm}"

This work perfectly fine with flex 3.6 , but when I compile it with flex 4.6 
the contextmenu doesn't show.

Thanks
