I Create a Component as follows:
TMyListView = class(TCustomListView)
constructor TMyListView.Create(AOwner: TComponent);
With Columns.Add do Caption:='AAA';
But when I try to put this component on a form (in design) I get an error: 'Control '' doesn't have a parent window'
This happens on the line: With Columns.Add do Caption:='AAA';
