NullReferenceException at remove when TreeView not visible
I got a crash when I remove an item from the model before the tree view is displayed for the first time (for example, when the item is hidden in another tab in a tabcontrol.
This happens only if I create the root TreeViewExItem in the XAML file
The crash is located at TreeViewExItem.cs in function "OnItemsChanged", in case "Remove", the ParentTreeView is null.
Could you please fix that?
