That is very unusual. TTreeView.Create should be defined as:
constructor Create(AOwner: TComponent); override;
A form is a TComponent so you should be able to pass it in as AOwner. Maybe
your new TTreeView version has a different Create constructor? In which case
I would suggest you modify your version to have AOwner as one of it's
parameters (and make sure you call "inherited Create(AOwner)" as the first
thing your constructor does.
