"No Jpf.Forward ..." error for nested controller

[Li]

Hi all,

I created a controller for login process, and added Jpf tag for begin
method:
@Jpf.Action(
       forwards = {
           @Jpf.Forward(name = "success", path = "login.jsp")
       }
   )
protected Forward begin(ReturnToForm initForm) {
......
}

But when I was compiling the application. It threw a error :
"There is no Jpf.Forward annotation with returnAction attribute defined for
my nested Controller" ....

Any idea?
