This is the code that worked in version 6.16:
======================================
Code in webapplication.java
======================================
protected void init()
{
super.init();
getDebugSettings().setAjaxDebugModeEnabled(false);
addComponentInstantiationListener(new
SpringComponentInjector(this));
getApplicationSettings().setPageExpiredErrorPage(PageExpiredErrorPage.class);
getApplicationSettings().setInternalErrorPage(InternalErrorPage.class);
}
public Session newSession(Request req, Response res)
{
return new EMSEVASession(req);
}
=======================================
After upgrading to version 6.20, the following error is observed in console:
======================================================
