Hi, I really need help with this one for work. I am making an application with multiple forms and therefore going back and forward capabilities. I am implementing the back capability which puts into display the last form submitted but when I try going forward from that form I get an IllegalStateException ?
Isn't it supposed to work like that ? Just putting into display other forms ?
Thanx
