Grails - binding a customized date format

It has been possible to bind a date directly since long before Grails 1.3. The steps are:

(1) Create a class that registers an editor for your date format under grails-app/utils:

import org.springframework.beans.PropertyEditorRegistrar
import org.springframework.beans.PropertyEditorRegistry
import org.springframework.beans.propertyeditors.CustomDateEditor
import java.text.SimpleDateFormat

public class CustomDateEditorRegistrar implements PropertyEditorRegistrar {

    public void registerCustomEditors(PropertyEditorRegistry registry) {

        String dateFormat = 'yyyy-MM-dd'
        registry.registerCustomEditor(Date, new CustomDateEditor(new 
        SimpleDateFormat(dateFormat), true))
    }
}

(2) Make Grails aware of this date editor by registering the following bean in grails-app/conf/spring/resources.groovy

beans = {
    customPropertyEditorRegistrar(CustomDateEditorRegistrar)
}
