Using Q1 2009 Demos...  
When we add a new row to the  child grid, the same value is updated in the last row.
When I click the right button on that row, an error appears.

System.NullReferenceException: Referencia a objeto no establecida como instancia de un objeto.
   en Telerik.WinControls.UI.GridViewCellInfo.get_CellElement()
   en Telerik.WinControls.UI.GridDataCellElement.MergeMenus(IContextMenuManager contextMenuManager, Object[] parameters)
   en Telerik.WinControls.UI.GridViewContextMenuManager.ShowContextMenu(IContextMenuProvider contextMenuProvider)
   en Telerik.WinControls.UI.BaseGridBehavior.OnContextMenu(MouseEventArgs e)
   en Telerik.WinControls.UI.BaseGridBehavior.OnMouseDownRight(MouseEventArgs e)
   en Telerik.WinControls.UI.BaseGridBehavior.OnMouseDown(MouseEventArgs e)
   en Telerik.WinControls.UI.RadGridView.OnMouseDown(MouseEventArgs e)
   en System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks)
   en System.Windows.Forms.Control.WndProc(Message& m)
   en System.Windows.Forms.ScrollableControl.WndProc(Message& m)
   en Telerik.WinControls.RadControl.WndProc(Message& m)
   en System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   en System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   en System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Note: For the first child grid this not happen.
