    Using silverlight 2 beta 2.

    When I enter a new value in a field of the datagrid the whole application goes blank. I don't get a message in the debugger, but I get the following message in the browser:



    Sys.InvalidOperationException:ManagedRuntimeError error #4004 in control 'Xaml1':System.NullReferenceException: Object reference not set to an instance of an object. at System.Windows.Data.BindingExpression.UpdateValue() at System.Windows.Data.BindingExpression.TargetLostFocus(Object sender, RoutedEventArgs e) at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args) at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, InPtr unmanagedObjArgs, Int args TypeIndex, String eventName) Code:0



    I can't find more information about this. Can anyone shed some light on what might be happening?

    Thanks
