[ https://issues.jboss.org/browse/WFLY-3804?page=com.atlassian.jira.plugin.... ] roman jablonka commented on WFLY-3804: -------------------------------------- I have done alike the discription Steps to add any new JSF implementation or version to WildFly on WildFly 8.1.0 final and test ist with the provided test application there for mojarra-1.2_15 which works as expected myfaces-2.1.14 which works as expected myfaces-1.2.12 which produces exception while deployment, and is marked deployment failed. MyFaces 1.2.12 is an implementation of Faces 1.2, so I would expect, it is working at WildFly. if nessesary, I can provide the slot installation cli and of course the testapplications. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
