    Need help with s:viewAction

    Assen Todorov Newbie

      Hi,


      I cannot get s:viewAction work. I try to use it exactly as specified in the seam 3 documentation, but without success.


      This is my page


      <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <ui:composition xmlns="http://www.w3.org/1999/xhtml"
                      xmlns:ui="http://java.sun.com/jsf/facelets"
                      xmlns:h="http://java.sun.com/jsf/html"
                      xmlns:f="http://java.sun.com/jsf/core"
                      xmlns:s="http://jboss.org/seam/faces"
                      xmlns:dms="http://www.ligatus.com/jsf/tags"
                      template="../../resources/templates/default.xhtml">
         <ui:define name="metadata">
            <f:metadata>
               <f:viewParam name="id" value="#{selectedId}"/>
               <s:viewAction action="#{engine.selectedItem(selectedId)}"/>
            </f:metadata>
         </ui:define>
      ...
      



      and this is my template


      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml"
            xmlns:h="http://java.sun.com/jsf/html"
            xmlns:ui="http://java.sun.com/jsf/facelets"
            xmlns:f="http://java.sun.com/jsf/core">
      <f:view>
         <ui:insert name="metadata"/>
      <h:head>
         <title>DA Engine</title>
         <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
         <link rel="stylesheet" href="/resources/css/default.css" type="text/css" media="screen"/>
      </h:head>
      <h:body>
      
      ...
      
      </h:body>
      </f:view>
      </html>
      



      After successful deploy I get this exception if I click on the link that goes to this page

      The exception basically says that org.jboss.seam.faces.ViewAction could not be found.
      I deploy an ear-file and seam-faces 3.0.0.Final is definitely in the lib directory in the ear-file along with other seam 3 artefacts.


      Can someone help mi with this issue?
