The reason was this in faces-config.xml: | <application> | <el-resolver>org.jboss.seam.jsf.SeamELResolver</el-resolver> | </application> | The USOE is gone after removing it. Another new change was also made to the default web.xml, added: | <listener> | <listener-class>com.sun.faces.config.ConfigureListener</listener-class> | </listener> | It works fine without it, so if anybody knows why we need this, speak up.
