You are correct here Michael. I thought that the state was not even getting
invoked, however it seems that the exception is raised in the state itself.
i have localised the line where it falls over
First, Here is the stack trace

here is where it falls over in our promptLogin state
// Fill in the Login field with values in following priority:
form-cache, cookie
Input loginName = new Input();
loginName.setName("LoginName");
String ln = StringUtil.notNull(request.getParameter("LoginName"));
if (ln.equals("")) {
// if LoginName is empty then perform this check otherwise use it
System.out.println("15");
ln = StringUtil.notNull(response.getFormCache("LoginName")); // ERROR
HERE
System.out.println("16");
if (ln.equals("")) {
ln = request.getUser();
}
if (ln.equals("NONE")) {
ln = "";
}
if (ln.equalsIgnoreCase("admin")) {
ln = "";
}
}
we are creating the inputs for login and password, the ouput only shows "15"
and doesnt get to "16".
Thanks for your help

Eddie,
I need a stack trace there. I use other forms in several 5.3 projects, so
you shouldn't be getting that class cast exception. My guess its that the
'validate' flag is triggering some code somewhere in Expresso.
We'll get this worked out!
