package ca.corbett.forms.validators
All FormFields support optional validation in the form of a FieldValidator.
Each FormField can have zero or more FieldValidator instances assigned to it.
These validators will be invoked on the field when the FormPanel is validated.
A validation success or failure label will appear next to the FormField automatically,
with helpful tooltip text as needed.
You can, of course, provide your own FieldValidator implementation, if you have specific business logic or validation rules that you need to use.
If multiple FieldValidators are assigned to a FormField, they will each be invoked, and all of them must return a successful validation in order for the field to be considered valid.
