Echo Web Framework

Hi All,

logout using IE7 works fine;
When it comes to Mozilla Firefox version-3, logout works fine but redirecting to login page does not work and browser gets hung up. When that page gets refreshed, then only it takes me to login page.

When i checked firefox error console, it was showing below error.
E_initialize is not defined.

The following is the code for logout action event,

MyEchoInstance echoInstance = (MyEchoInstance)getEchoInstance();
String servletContextPath = echoInstance.getServletContextPath() + "/controller";
ServerContext sc=(ServerContext)echoInstance.getAttribute(ServerContext.ATTRIBUTE_NAME);
HttpSession session=sc.getSession();
session.invalidate();
sc.exit(servletContextPath);

Please suggest.

Thanks,
illi
