zhifu Jin commented on RF-12268:
--------------------------------

I got code, and run on tomcat7.0.27 had this error on rf-12268.xhtml page: javax.faces.view.facelets.FaceletException: javax/servlet/jsp/jstl/core/LoopTagStatus
and I got nothing about log and console output. I checked the jstl lib of mine is 1.2 version. How I can enable the log of metamer application?
