This appears to be a bug.
I have a form with grouped variables. Only one of which is required (set NOT NULL in MySQL). When setting attributes, I give it the following:
[dim_height]
group = "Container characteristics"
widget:label = "Height"
validators:regex = "/[0-9]/"
widget:atts:size = 3
However, with this set, the data in the form never saves to my database. Only by commenting out 'group ?' will it save.
Or am I missing something?
