/**
 * Rather than using Wicket's required field validation, which doesn't play well with Ajax and forms,
 * allow validation of fields on actions. User must call this from the action method.
 * Adds errors to the page if empty required fields are found. 
 *
 * @return true if validation was successful, else false if errors were found.
