Currently, setting either DataSource or Delegate property to null results in an ArgumentNullException.
Comment 1 Ram Chandra 2014-10-01 08:33:03 UTC
I can reproduce the reported behavior. When I try to set the datasource and delegate property of "outline view" to null I am getting null reference exception . I’ll need confirmation from the developer if this is a bug. Leaving as NEW for now.
