component Tree Tomahawk

Bonjour,

Je souhaite utiliser le composant Tree de l'api tomahawk.

J'obtiens l'erreur suivante :
javax.servlet.ServletException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered.

Et pour utiliser les composants de l'api commencant par t: ( exemple : t:tree2)
J'ai renseigné mon web.xml comme suivant :

<filter>
<filter-name>extensionsFilter</filter-name>
<filter-class>org.apache.myfaces.webapp.filter.ExtensionsFilter</filter-class>
<init-param>
<param-name>uploadMaxFileSize</param-name>
<param-value>100m</param-value>
</init-param>
<init-param>
<param-name>uploadThresholdSize</param-name>
<param-value>100k</param-value>
</init-param>
</filter>

<context-param>

<param-value>/WEB-INF/faces-config.xml</param-value>
</context-param>

</filter-mapping>

<url-pattern>*.faces</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.htm</welcome-file>
</welcome-file-list>

Quelqu'un voit pour quelle raison, j'obtiens l'erreur : ExtensionsFilter not correctly configured.

Merci de votre aide.
