Can anyone explain why I can control the message for @Pattern, but the message for @NotNull is ignored.

Explanation:

If I annotate a field on an @Entity with these annotations

@NotNull(message="field is null")
@Pattern("^\W$",message="field not valid")

and then reference the entity in a JFS/Facelets page like this

<h:messages/>
<h:inputText value="#{entity.name}" required="true">
 <s:validate/>
</h:inputText>

and then test it, the @NotNull message doesn't doesn't display. I get the default message: {0}: Validation Error: Value is required.

But, when I test it for the Pattern validation, the @Pattern message DOES display!?

I haven't tested using a message.properties, and from what I know, we don't have one (though there could be a default one in a jar somewhere that is setup for NotNull but not Pattern.)

Can anyone clear this up for me?
