Hiding rich:messages span when no messages exist

[anilarora]

As part of the migration from RF 3.3.0 to RF 4.2.3.Final, I found an issue with how rich:messages behaves when there are no messages.  It keeps the rendered <span> even when no messages exists.

This causes a problem because we want to decorate the message box with a background color.

<rich:messages id="errorMessage" styleClass="yx-message" layout="list" />

And what gets rendered is

<span class="rf-msgs yx-message" id="errorMessage"></span>

Unfortunately, this shows up as an empty box with the background color. 

Any thoughts?  Workarounds?  I wasn't able to find anything to allow me to use the rendered attribute in a <ui:fragment> to hide this span.

I forgot to add that this behavior is different than 3.3.0 which put a style="display:none" when the messages were empty.

I'm not sure if this was a response or not...what does this mean?
