Before I do a redirect which requires parameters,
I have a java class which I instantiate to provide
parameters.
RedirectParameters rp = new RedirectParameters();
rp.add("param1",myParam1String);
rp.add("param2",myIntParam);
rp.add("sameParamName",diffValue1);
rp.add("sameParamName",diffValue2);
rp.add("sameParamName",diffValue3);
I recently added support for adding an ActionError
and/or ActionMessage object.
The params are saved as a request attribute.
In the RequestProcessor,
I check if the ActionForward is for a redirect.
If it is and if this attribute is present,
I append the params to the redirect URL.
Wish I'd thought of adding it to ActionForward.
That would make the approach feel a lot cleaner.
On the other hand, that would have a bigger
footprint either on the engine or on the
Action returning the ActionForward for
thread safety, etc. Not to mention saying goodbye to
the [ return mapping.findForward("myMapping"); ]
lines. =)
