RE: Re: Re: Issue with myfaces sandbox component

Strangely enough, though, I added the tag class to the taglib.xml file,
and it's trying to load the converter but I'm getting the following
exception. It appears myfaces can't find the converter, however, it's on
the classpath. It's in my web-inf/lib directory.

Unless the tag is badly-written, no.

The Tag file would only be used in a JSP environment -- facelets
replaces the entire Tag functionality with the taglib.xml file.
