Hi all,
I am still struggling with the same problem , Did anybody have any
solution/thoughts ?
I have a problem with forwarding the request to an action.
I am using validations for the fields mention on the form , once validation
fails as struts defined it will check for result name "Input".
If the result name "Input" is defined with result type "redirect-action" as
shown below , this will forward to the mention action with new request.
<result name="input" type="redirect-action">
Is there any way where I can forward to an action , but still can use the
old request object, throught will I can display the invalid values that user
enter.
I tried all the result type like :
dispatcher --- Dispacther uses the old request object but the location must
be a view not an action.
Chain --- chain uses the old request object but it is excuted irrespective
of what happen , life even if the validation pass chain is going to exucute.
redirect -- same as redirect-action.
Do anybody got such a problem earlier. ?
Temp solution :
I am setting the values in the session in the getter method of the object.
and setting back to the new request removing it from the session.
But i think this is a temp solution , there should be a direct solution
where we can speicfy in resut-type like redirect with the old request
object.
Please any Inputs are highly appreicated.
