Datatables Editor Validation - How to require at least one checkbox group item to be selected

terry.farquhar@jhuapl.edu

How can I make a checkbox field required? I want to require at least one item to be selected in specific checkbox group and the following code doesn't seem to work as it does the other form fields.

->validator( 'Validate::required' )

*My checkbox list is dynamically created btw.

Thank you!

Is this with an Mjoin? If so, then use the validation methods discussed here.
