    Configurating seam for facelets and myfaces-tomahawk

      Configurating seam for facelets and myfaces-tomahawk :

      I have added successfully some tomahawk elements to the current seam-booking example (jboss-seam-1.0.0.CR2), running in jboss-4.0.4.CR2, following these steps:

      1- Obtain the file tomahawk.taglib.xml from the site of facelets:
      http://wiki.apache.org/myfaces-data/attachments/Use_Facelets_with_Tomahawk/attachments/

      2- Put tomahawk.taglib.xml in WEB-INF/

      3- Put tomahawk.jar in WEB-INF/lib
      This version of tomahawk.jar is taken from the seam-issues example

      4- Add to web.xml :
      <context-param>
      <param-name>facelets.LIBRARIES</param-name>
      <param-value>/WEB-INF/tomahawk.taglib.xml</param-value>
      </context-param>

      5- Add to the screen file:
      xmlns:t="http://myfaces.apache.org/tomahawk"

      Now you can add the elements <t:> to the screen file.

      I can run the example with success testing elements as <t:outputText> and <t:dataTable>

      But I got an exception when I added the element <t:dataList>
      The exception says:

      As conclusion, in this facelet example some tomahawk elements run fine and another elements fail.

      I think that there are problems of compatibility between the libraries of the application (included seam libraries) and the libraries of the server.

      Has anyone some solution to this problem ?

      Thanks for your answers.
