Hello. I want to port our webapp to seam-2.0 and use myfaces-core-1.2, jbossas-4.2.1 and the tomahawk-components-1.1.6. I followed the instructions from http://wiki.jboss.org/wiki/Wiki.jsp?page=JBoss5AndMyFaces and the seam2migration.txt. The application starts and is working. But MyFacesConfig/jboss shows an errormessage on stdout anonymous wrote : | Both MyFaces and the RI are on your classpath. Please make sure to use only one of the two JSF-implementations. | In debugmode i figured out, that the current classloader of the deployed webapp only include the myfaces-jars? Is this message a bug on the myfaces-classes or do i have to change the classpathconfiguration. By the way, how could i do this.
