    Javascript error

    ARUN PRAKASH GANESAN Newbie

      I am doing a request forward on one of the pages in my app.
      When i forward it to the page i get a javascript error says

      "Syntax error on line 13". Line 13 has the following code which richfaces is inserting

      if (typeof A4J != 'undefined') { if (A4J.AJAX) { with (A4J.AJAX) {if (!EventQueue.getQueue('org.richfaces.queue.global')) { EventQueue.addQueue(new EventQueue('org.richfaces.queue.global',null,null)) };}}};window.RICH_FACES_EXTENDED_SKINNING_ON=true;


      Questions

      1. Why would richfaces want to insert javascript code on the head?
      2. The error does not occur in any of the pages except the pages which i do a requestdispatcher.forward...

      Suggestions?

            Hi,

            1. It's required by components

            2. Please post:

            - pages code
            - Java code that is actually used to do forward
            - web.xml contents

                Saikiran Madhavan Newbie

                How can we ignore certain URLs from the Ajax Filter processing. In my application, i want to ignore certain URLs and for that i have a custom filter class.

                How can we do the same thing with the org.ajax4jsf.Filter. I am using the below given context param configuration

                <filter>
                 <filter-name>richfaces</filter-name>
                 <display-name>Ajax4jsf Filter</display-name>
                 <filter-class>org.ajax4jsf.Filter</filter-class>
                 <init-param>
                 <param-name>forceparser</param-name>
                 <param-value>false</param-value>
                 </init-param>
                 </filter>
                <context-param>
                 <param-name>org.ajax4jsf.xmlparser.ORDER</param-name>
                 <param-value>NEKO,TIDY,NONE</param-value>
                 </context-param>
                

                for my custom filter this is the configuration i have

                <filter>
                 <filter-name>RequestIntercepter</filter-name>
                 <filter-class>org.ets.ibis.web.filters.TimeoutFilter</filter-class>
                 <init-param>
                 <param-name>session</param-name>
                 <param-value>user</param-value>
                 </init-param>
                 <init-param>
                 <param-name>url</param-name>
                 <param-value>/sessionTimeout.faces</param-value>
                 </init-param>
                
                 <init-param>
                 <param-name>ignoreUrls</param-name>
                 <param-value>login.faces,sessionTimeout.faces,logout.faces,/resources/,/xmlsvcs/,/services,/Word,/Export,/Report,/exportFiles/,/external/,/registration/</param-value>
                 </init-param>
                 </filter>

                for the order of applying the filter. but still i am not able to ignore URLs.
                let me know any suggestions or hints for ignoring URLs from Ajax Filter.

                Thanks in advance
