Javascript error

apg9595 Sep 14, 2009 4:39 PM

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?

1. Here is the code

Hi,

1. It's required by components

2. Please post:

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

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>

and the filter class code is given below


/**
 *
 */
/**
public class TimeoutFilter extends IbisFilter {
 /**
 * session name to look for
 */
 private String session;

 /**
 * Reference context, for internal use only
 */

 }

 */
 public TimeoutFilter(){
 addRequiredProperty("session");
 addRequiredProperty("url");
 }

 if(o instanceof User) {
 User user = (User)o;
 //set current thread user
 ibisContext.setThreadUser(user);
 } else {
 logger.warn("Invalid session attribute [" + o + "]");
 throw new IllegalStateException("Invalid session attribute!");
 }

 //log it only when needed
 logger.debug("Total time to process the request - " + (System.currentTimeMillis()-start) + " ms");
 }

 //process
 filterChain.doFilter(request, response);
 } catch (IllegalStateException e) {
 request.getRequestDispatcher(url).forward(request,response);
 //response.sendRedirect(request.getContextPath() + response.encodeRedirectURL(url));
 return;
 }
 finally {
 //clean up after execution complete
 ibisContext.clearThreadUser();
 }
 }

 /**

 * @param request
 * @return
 */
 private boolean processRequestURI(HttpServletRequest request) {
 if(StringUtils.isEmpty(ignoreUrls))
 return true;

 //see if there are more than one

 for(int i = 0; i < urls.length; i++) {
 if(StringUtils.contains(requestURI, urls))
 return false;
 }

 //proceed
 return true;
 }

 }

 this.session = session;
 }

 /**

 public String getUrl() {
 return url;
 }

 public void setUrl(String url) {
 this.url = url;
 }

 /**
 * Setter for the property ignore URLs (comma delimited if multiple)
 * @param ignoreUrls
 */
 public void setIgnoreUrls(String ignoreUrls) {
 this.ignoreUrls = ignoreUrls;
 }

 /**
 * Ibis context setter
 * @param ibisContext
 */
 public void setIbisContext(IbisContext ibisContext) {
 this.ibisContext = ibisContext;
 }
 }

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
