spring.net multiple validators with one action.

I had an interesting problem at work the other day.
I needed to perform a number of validations against an object, and report a single error message.
In this project we're using Spring.net's validation framework.

Out of the box, spring.net validation doesn't provide any easy way to report a single error for multiple validations. But here's a simple trick to work around this:
1. Use a validation group to group all the validations.
2. Don't include an action (message) on the included validations.
3. Set the group's 'Actions' property to a new list of Spring.Validation.Actions.ErrorMessageAction items.

<v:group>
  <v:property name="Actions">
    <list>
      <object type="Spring.Validation.Actions.ErrorMessageAction">
        <constructor-arg index="0" value="error.MyError" />
        <constructor-arg index="1" value="MyErrorParam" />
      </object>
    </list>
  </v:property>

  <v:validator test="Prop1" />
  <v:validator test="Prop2" />
  <v:validator test="Prop3" />
</v:group>
