faces version problem

[armita]

I noticed that replacing the myfaces jar files with a 1.1.1 release make my application broke. I need to use tomahawk. Bu tit gives me:

19:56:57,264 WARN [HtmlRenderKitImpl] Unsupported component-family/renderer-type: javax.faces.Panel/org.apache.myfaces.PanelRenderer
19:56:57,264 INFO [[/mcipro]] No Renderer found for component {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /BTS.xhtml][Class: org.apache.myfaces.custom.collapsiblepanel.HtmlCollapsiblePanel,Id: test]} (component-family=javax.faces.Panel, renderer-type=org.apache.myfaces.PanelRenderer)
19:56:57,302 WARN [UIComponentBase] No Renderer found for component {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /BTS.xhtml][Class: org.apache.myfaces.custom.collapsiblepanel.HtmlCollapsiblePanel,Id: test]} (component-family=javax.faces.Panel, renderer-type=org.apache.myfaces.PanelRenderer)

I tryed to replace myfaces and tomahawk jar files, but then my converters also broke.
I wonder which version of myfaces is in the seam repository? And Why I am getting the above warning? Could someone please help me?
I am using seam head and jboss head

Make sure you clear your tld cache when you upgrade versions of jars that include JSP tags. for tomcat (or jboss) there should be a work folder that's a sibling to your web apps directory. delete the cached files and restart the container
