So I tracked this down to the following code:
(defmethod widget-children ((obj dataform) &optional type)
"Returns all widgets from all view fields with presentation
widget-presentation"
(let ((widgets))
(map-view-fields
(lambda (field-info)
(when (typep (slot-value (field-info-field field-info)
'presentation) 'widget-presentation)
(push (widget-presentation-widget (slot-value (field-info-field
field-info) 'presentation)) widgets)))
(dataform-form-view obj)
(dataform-data obj))
widgets))
Since widget-presentation-widget must be funcallable, there is no way that
it will be a widget; furthermore the view itself takes care of redrawing
itself when the dataform is dirty. Is it safe to just completely remove
this method?
