    JSF comparision operators don't work

    Jose Alvarez de Lara Novice

      Hi,

       

      I am trying in a xhtml file the following,

       

      <c:choose>
         <c:when test="#{_mensaje.respuesta.length() gt 10}">
           <h:link id="viewRespuesta" value="#{_mensaje.respuesta.substring(0, 9)}..." outcome="respuesta" style="white-space: nowrap;">
             <f:param name="id" value="#{_mensaje.id}"/>
          </h:link>
        </c:when>
        <c:otherwise>
           #{_mensaje.respuesta}
        </c:otherwise>
      </c:choose>
      

       

      What I pretend is if  the string length > 10 resume in a link, otherwise show the string.

      The problem is that  be what be the length of the string it always show the complete string

      And I do not know where the error is.

       

      Regards,

      Jose

          Regarding my issue I have two questions,

           

          1) The dependency I added is the one as follows,

           

          <dependency>

             <groupId>javax.servlet</groupId>

             <artifactId>jstl</artifactId>

             <version>1.1.2</version>

          </dependency>

           

          Is that correct?

           

          2) I have been googling and I have not could put light about the namespace,

           

          Is it xmlns:c="http://java.sun.com/jsp/jstl/core" or without /jsp/ as follows xmlns:c="http://java.sun.com/jstl/core"?

           

          Kind regards,

          Jose

            I have taken some information just googling.

             

            I mean,

            https://issues.jboss.org/browse/RF-7261

             

            So I have changed my code leaving as follows,

                                <h:commandButton action="#{mensajeAgent.cancel}" value="Cancel" />
                            </h:form>

                </ui:define>
            
            </ui:composition>
            

             

            but still does not work. It always selects the <c:otherwise> option and I am thinking

            if maybe I am wrong about the logic of the code.

             

            In the database the refereed field is type of varchar(255).

             

            Regards,

            Jose

              It is a Seam 3 project and I would like to know if JSTL is compatible with the framework.

              I have been googling and the only one question is about the namespace but I did not find to

              anyone saying that I can not use it.

               

              So I can not understand why it does not work.

               

              Regards,
