Hi Marco!

I think using only one jsp wherein the number of form elements vary
according to what you are doing can be considered as "anti-pattern" and
is more of a JSP Model 1 design. The best way to make things work is to
use a separate JSP for each form so that you can properly associate a
separate ActionForm with each ActionMapping.

If you wish to continue with the single jsp solution and still wish to
use DynaValidatorForm, you can write your own Validator class and
declare it in the validator-rules.xml. That way you can control how it
will behave and validate the parameters...

morality and politcs :o)

Hi Wendy,
	Only a little problem.. I haven't written any class for my
DynaActionForm. Instead, I declare all the properties in the
struts-config.xml

Struts does all the rest....

But, anyway, can u give more details on ur solution to my problem?

Regards
	marco

What about LookupDispatchAction?  It uses a request parameter to figure
out which method to call.  I use it with hidden form fields and a bit of
JavaScript.

In Marco's case, overriding the validate method might work.  Only call
super.validate() if all of the parameters are present.
