    <a4j:push> issue: RichFaces.Push.setPushResourceUrl is not a function

    j0sh Newbie

      Hello community,

       

      i've got a problem regarding the <a4j:push> component.

       

      Here my project configuration:

       

      - Maven project

      - JSF 2 with Richfaces 4.1.0-SNAPSHOT

      - Spring Framework as IoC Container

       

      Now i have the following problem: whenever i start my tomcat server and run my application, the push renderer or something else includes the wrong push.js javascript file.

       

      In my project libs the push.js looks good. The file is located in the META-INF folder of the richfaces-components-ui-4.1.0-SNAPSHOT.jar file under /META-INF/resources/org.richfaces/push.js. If i look into this javascript file there is a function called setPushResourceUrl. But the content of the loaded push.js file (<path/to/project>/faces/javax.faces.resource/push.js?ln=org.richfaces) in my app is not the same as the push.js file in the richfaces-components-ui-4.1.0-SNAPSHOT.jar? But where this push.js comes from?

       

      Here is the code of the loaded push.js:

                      this.__unbindErrorHandler();
      
                      richfaces.Push.decreaseSubscriptionCounters(this.__address);
                      $super.destroy.call(this);
                  }
              });
      
          // define super class link
          var $super = richfaces.ui.Push.$super;
      
      }(jsf, window.RichFaces, jQuery));
      

       

      As you can see, there is a setPushResourceUrl in the version which is located in the jar. I dont know where the 'wrong' version comes from.

       

      Can anyone help me?

       

      Best,
