I have a feature layer with attachments enabled for editing. The feature layer includes a required (no null value) string field that is blank for users to provide necessary details/comments. When I edit the layer and add text to this blank string field - the addition of attachments fail. But if i apply a default answer for this field and/or a choice list, the attachments work.
I experienced this same behavior with feature layers and layer views.
Anyone else seeing this type of behavior?
