    Facelets custom EL functions in JBoss 4

    MOOS Hoos Newbie

      Hello

      We migrate a web application that is deployed on a Tomcat 5 application server with a JVM 1.4 and JSF 1.1 to a JBoss 4 application server, a JVM 1.6 and JSF 1.2.

      In this application, we use Facelets custom function for make string concatenation in a ouputText tag.

      <h:commandButton class="bouton" id="boutton1"
       value="#{monBean.value}"
       actionListener="#{monBean.doAction}">
       </h:commandButton>
      
      ....
      
      <h:outputText value="#{<my_resource_bundle>[mycustomtag:concat(chaine1,chaine2)]}" />
      
      


      mycustomtag.taglib.xml
      <!DOCTYPE facelet-taglib PUBLIC
       "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
       "http://java.sun.com/dtd/facelet-taglib_1_0.dtd">
      
      <facelet-taglib xmlns="http://java.sun.com/JSF/Facelet">
       <namespace>http://mycustomtag</namespace>
       <function>
       <function-name>concat</function-name>
      
       <function-class>com.MaClasseUtil</function-class>
       <function-signature>
       java.lang.String concat(java.lang.String, java.lang.String)
       </function-signature>
       </function>
      </facelet-taglib>
      
      


      In the web.xml i have this
      <context-param>
       <param-name>facelets.LIBRARIES</param-name>
       <param-value>/WEB-INF/tomahawk.taglib.xml; /WEB-INF/mycustomtag.taglib.xml</param-value>
       </context-param>
      


      the first load of my page, my tag is working properly.
      But once I click on my button (it's a submit), my page no longer works, and I get an exception wich say's :

      javax.el.ELException: /user/profilDetail.jsp @252,91 value="#{referentielLabels[montag:concat('profil.typeDonnee.', typeDonnee)]}": Function 'mycustomtag:concat' not found
      



      I saw a number of lifts have been warning about JBoss facelets and EL function. Does someone have an answer ?

      thx !
