Hello Clevelam, Did you get any solution on it.? I too am running with same problem... The error is because(possible reason) in Login.jsp, the form submission target is parent which is as shown here, | | <form method="POST" name="loginform" action="/portal/LoginServlet" id="loginForm" target="_parent" | style="margin:0;padding:0"> | But not got the solution yet, If you got any solution then let me know.
