> Whenever "FacesMessages.createFacesMessage(Severity severity, String messageTemplate, Object... params)" is called, the message is fully interpolated.  Meaning, it will resolve EL expressions inside of the message itself.  When "FacesMessages.createFacesMessage(Severity severity, String key, String defaultMessageTemplate, Object... params)", it does not do this full EL expression resolution.  The code changes below would probably support this.
