Hello again,
hmmmmmmm... Hopefully, I did not ask a too silly thing. I try again.
I'am not sure, if I use request parameters correctly. Like I use them, I
would need to manipulate the request (removing some parameters) before
forwarding occures.
I use request parameters to specify required actions. I use them in forms
(form actions and the form button names) and in usual hyperlinks. Lets
assume a hyperlink:
jsp page something.jsp:
...
<html:link page="/something.do?action=next">
...
SomethingAction's perform method:
// ...
// check for errors
// ...
// change underlying model. (retrieve next record)
// ...
// forward to original jsp.page and display the changed model
return (new ActionForward(mapping.getInput()));
Until now everything works fine, but the original request url is still
valid. Pushing the reload button of the browser causes a "next" action
again. It should cause a simple reload.
Could someone tell me, what I do wrong?
Thank You,
Stefan
