Thank you Massimo, The expected behavior is for the 'list:string' field to be a required field in order for the form to pass validation.
It is currently a jquery multi-select checkbox dropdown created from an IS_IN_SET(...zero=None) validator on the same field (which works perfectly to my knowledge). I'm fairly certain there is a simple way to accomplish what I want to do but I'm not seeing it. The idea is to have a custom error message like 'Please select one or more...bloggittyblahblah'. I have a validator in the form which works great for an empty string, sadly though my list:select will submit no matter what I do whether there are options selected or none selected. How can I implement something like IS_NOT_EMPTY() to require the field have a value to pass validation with a 'list:string' field?
