Hi Mort,
You need to include at least one widget that can be managed by
AUTO_WID_MNG (and use the /auto keyword in that widget definition.
For instance:

base = widget_auto_base()
wg = widget_slabel(base, prompt = 'My List')
wm = widget_multi(base, list=['1','2'], uvalue='list', /auto)
result = auto_wid_mng(base)
