Error message when i use AddOutline and FreezeToCell together

Version 2.0.1 WPF

When I use the following functions togethers :
                sheet.AddOutline(RowOrColumn.Column, 5, 2).Collapse();
                sheet.FreezeToCell(2, 7, FreezeArea.LeftTop);

I had this error message : Object reference not set to an instance of an object

Stacktrace :

   à unvell.ReoGrid.Views.ViewportController.AddView(IView view)
   à unvell.ReoGrid.Views.NormalViewportController.CreateOutlineHeaderViewIfNotExist()
   à unvell.ReoGrid.Views.NormalViewportController.Freeze()

When i use one of this functions alone everything works

best regards

I just tested this with a blank worksheet and your test code, I can't get the problem happen.
