Unable to fix 'but no tag was defined for name: form' error
legit Feb 24, 2011 9:32 AMI'm new to richfaces development and am starting with a very basic app, I wanted to test some a4j functionality but am getting the following error when trying to view my page:
javax.faces.view.facelets.TagException: /index.xhtml @14,16 <a4j:form> Tag Library supports namespace: http://richfaces.org/a4j, but no tag was defined for name: form
Despite a day of messing around with web.xml configuration and adding/subtracting jars from my war I can't seem to figure out why I'm getting this error. Can anyone help me understand what is going on?
my web.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
