DataDialog:ToolBar returns always NULL, even if a toolbar object is assigned

Attached sample fails with an ArgumentNullException on this code

METHOD PostInit(oWindow,iCtlID,oServer,uExtra) // datadialog
    SELF:Menu := StandardShellMenu{}
    SELF:ToolBar := SELF:Menu:toolbar // menu does have a toolbar
    SELF:ToolBar:Show() // null exception here

Problem is because of this code in ChildAppWindow.prg:

ACCESS ToolBar
	IF oImp IS AppWindow VAR appWnd
		RETURN appWnd:Toolbar
	ENDIF

Original code in VO was checking for the Window class instead of AppWindow.

Should be fixed
