    Richfaces 4.5 - wrong reference to spacer.gif

    johannes2014 Newbie

      Richfaces 4.5.17.Final (after upgrading from 4.3.6.Final)

      This error also shows up with 4.5.9.Final

       

      After upgrading from 4.3.6.Final to Richfaces 4.5.17.Final I see the following Exception when I open I page including an rich:extendedDataTable:

       

      13:50:08,594 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/myapp].[Faces Servlet]] (http-127.0.0.1:8080-1) JBWEB000236: Servlet.service() for servlet Faces Servlet threw exception: java.lang.UnsupportedOperationException

      The cause for this is that there is a missing reference to spacer.gif:

      http://localhost:8080/myapp/javax.faces.resource/spacer.gif.myportal-resource?ln=org.richfaces&v=sLjXbVU

       

      The spacer.gif is loaded in

      http://localhost:8080/myapp/org.richfaces.resources/javax.faces.resource/org.richfaces/extendedDataTable.ecss?db=eAG7dPvZfwAIqAOT

       

      This is how extendedDataTable.ecss looks rendered in the browser:

      .rf-edt-rsz {

      background-image: url(/ddsadmin_2/javax.faces.resource/spacer.gif.myportal-resource?ln=org.richfaces&v=sLjXbVU);

      cursor: e-resize;

      height: 20px;

      position: absolute;

      left: 100%;

      margin-left: -3px;

      width: 6px;

      }

       

      and how extendedDataTable.ecss looks like in the WAR:

      .rf-edt-rsz {

        background-image: "#{a4jSkin.imageUrl('spacer.gif')}";

        cursor: e-resize;

        height: 20px; /*TODO*/

        position: absolute;

        left: 100%;

        margin-left: -3px;

        width: 6px;

      }

       

      This is how to fix it yourself easily by overriding the css class (see also Chapter 3. RichFaces overview ):

      Override the CSS class and remove the background-image reference:

       

      <h:outputStylesheet target="head">

      .rf-edt-rsz {

          background-image: none;

      }

      </h:outputStylesheet>

       

      The error itself has nothing to do with the skin used (I turned it off using org.richfaces.enableControlSkinning=false in web.xml), I verified it also occurs with blueSky or DEFAULT.

      The spacer.gif is present in richfaces-4.5.17.Final\META-INF\resources\org.richfaces.staticResource\4.5.17.Final\PackedCompressed\blueSky\org.richfaces.images\spacer.gif.

       

      The error is caused by a wrong reference to the existing spacer.gif:

       

      The correct rendered reference would be

      This is the wrong reference rendered in the ecss file:

      http://localhost:8080/myapp/javax.faces.resource/spacer.gif

       

      This it how it should look like (this reference works):

      http://localhost:8080/myapp/org.richfaces.resources/javax.faces.resource/org.richfaces/spacer.gif

      So the "org.richfaces.resources" is missing.
