The piece you are missing is registering of the new property editor. The following worked for me when I upgraded to Grails 1.1 and had to bind dates in the MM/dd/yyyy format.

grails-app/config/spring/resources.groovy:

beans = {

src/groovy/util/CustomPropertyEditorRegistrar.groovy:

package util 

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

public class CustomPropertyEditorRegistrar implements PropertyEditorRegistrar { 
  public void registerCustomEditors(PropertyEditorRegistry registry) { 
      registry.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("dd/MM/yy"), true)); 
  } 
}
