i sent the below message to struts-user a couple of days ago. since that time i tried to address the problem by creating a subclass of RequestProcessor and overriding the process method. didn't work.
i figured i could make an "unfrozen clone" of the mapping to pass into processValidate, which would allow my form to set the input path inside its validate method. unfortunately, there was no clean way to do this; i didn't want to cut and paste processValidate into my subclass, and there is no hook within process to allow a subclass to step in and create the mapping clone.
i wound up having the form set a session attribute which the action then gets and removes. a grotesque solution to be sure, but the only apparent alternative was worse.
so the question i put to you folks is: how must struts change to allow me to modify the mapping's input path inside the form's validate method? or is there some existing solution that i'm completely missing?
thanks!

i'm using struts 1.1b2 to perform a simple validation on an action form. it works great, except:
when validation fails, i need to specify an additional request parameter for the input path, as the input page requires that parameter to exist. unfortunately, i get a "configuration frozen" error when i try to modify the input path in the action form's validate method.
i've considered but rejected using a session attribute instead of a request parameter for this particular piece of data. other than that, is there a solution that i'm missing?
thanks!
