Having validators on all widgets seems to be a must have since it allows to perform higher-level validation on e.g. repeaters, forms, etc. Currently, a validation rule is supposed to return a ValidationError which is attached to the widget invoking the validation rule.
This has several problems:
- not all widgets can provide visual feedback for a validation error, i.e. a form, a repeater or a class.
It can be fixed with styling change, and/or with a patch I suggested a while ago. I can commit it, I still have it (<wd:validation-error/> tag)
