Ui:hyperlink and ui:button "action" methods stopped working in IE

Question

Hi
I'm developing my application for few months, but few days ago all ui:hyperlink and button action methods stopped working in IE. They are not invoked at all... No javascript errors, everything works fine in Firefox. Can anybody tell me where to look as I'm sitting 6h in front of screen and cannot find anything wrong...
The only thing I have changed was adding a filter which changes encoding to UTF-8. Class below:
* CharsetFilter.java
* Created on 17 maj 2007, 11:18
package tools.filter;
import java.io.*;
import java.net.*;
import java.util.*;
import java.text.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
* @author  Michal
* @version
public class CharsetFilter implements Filter {
    public CharsetFilter() {
    private String encoding;
    public void init(FilterConfig config) throws ServletException {
        encoding = config.getInitParameter("requestEncoding");
        if( encoding==null )
          encoding="UTF-8";
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain next)
         throws IOException, ServletException
//          request.setCharacterEncoding(encoding);
          next.doFilter(request, response);
     * Destroy method for this filter
    public void destroy() {
}

anyways, it can't be a problem becasue new application is facing the same problem and there's no filter. I'm using tomcat 5.5.18 on jboss 4.0.5.
