keepvalues is for retaining values when there are no errors (but you want to retain the values from the previous submission). If there are errors, the values will be retained regardless of keepvalues. In your case, you are not using form.custom.widget, so you're not getting the values retained. If you create custom widgets, though, the field and value will get passed to the widget, so your custom widget should be able to retain the value if desired (without using request.vars).
