11 in a JBoss 5.1.0 and I am getting the following error :

Error: javax.faces.application.Application.createComponent(Ljavax/faces/context/FacesContext;Ljava/lang/String;Ljava/lang/String;)Ljavax/faces/component/UIComponent;

I have tried several changes in the deployment descriptor and removing myfaces and el jar files from the project but none worked

my web.xml is as follows :

    <description>
        A very common problem in configuring MyFaces-web-applications
        is that the Extensions-Filter is not configured at all
        or improperly configured. This parameter will check for a properly
        configured Extensions-Filter if it is needed by the web-app.
        In most cases this check will work just fine, there might be cases
        where an internal forward will bypass the Extensions-Filter and the check
        will not work. If this is the case, you can disable the check by setting
        this parameter to false.

I have also created a jboss-classloading.xml in WEB-INF directory in my war file with the following content :

    <classloading xmlns="urn:jboss:classloading:1.0"
                  name="myfaces-example-simple20-1.1.11.war"
                  domain="localhost">

                  parent-domain="Ignored"

                  export-all="NON_EMPTY"
                  import-all="true">
    </classloading>

Can you guys help us out on this ? I can not change the JBoss version ...
