We have an app that allows people to add elements to a ListMultipleChoice by pressing on a button. We want the form to fail validation if the ListMultipleChoice contains no elements.
I've tried this: targettedSetsList.add(new IValidator() { public void validate(IValidatable validatable) { // Always contains no items - strange Collection list = (Collection)validatable.getValue(); if ( list.size() == 0 ) { ValidationError ve = new ValidationError(); ve.setMessage("No sets have been specified for deployment"); validatable.error(ve); } } }); but at validation the list.size() is always 0 even if the user has added elements. Am I doing it the right way? Is there a better way?
