Now i've got: Columns and TVirtualStringTree.Columns

The problem is that Columns is a property of Header 
(TVirtualStringTree.Header.Columns).

Previously Columns where streamed as a direct child of  
TVirtualStringTree using DefineProperties method as a workaround to 
Delphi bug. I removed this hack and now Columns is streamed as child of 
Header.
Is there any method, other than DefineProperty, that can change a 
property hierarchy?

FYI Columns.GetOwner returns the Header instance.

I called both GetValue (0 items) and inherited GetValue (Unknown).
