Hi,
so I must understand that it?s not possible to pass parameters in the
request beetwen chained actions, is it?
Is not there a way to change a parameter value of the request if both
actions use the same ActionForm? I want to modify one of the parameters in
the firs action, so second action (chained action) can see the change.
Although I know it may be a bad idea, I don?t have any other now!! :-(
