This is a facelets issue, not a myfaces issue.
Make sure you've registered your converter in a taglib.xml file. For example,
<tag>
<tag-name>optionalConverter</tag-name>
<converter>
<converter-id>net.sf.jsfcomp.validator.OptionalConverter</converter-id>
</converter>
</tag>
If you've done that, then I'd recommend asking on the facelets user
mailing list.
