TListView with LiveBindding

Hello

Using the XE10 trial ver. I try the ListView tutorial from the DocWiki.

When I create the OnButtonClick ListView event It's create the code:

procedure TForm1.ListView1ButtonClick(const Sender: TObject;
      const AItem: TListItem; const AObject: TListItemSimpleControl);

and on the tutorial the code is:

procedure TForm1.ListView1ButtonClick(const Sender: TObject;
  const AItem: TListViewItem; const AObject: TListItemSimpleControl);

Why it's different?

Thanks Sorin
