hello, not very sure but iguess make ur custom form class by extending the DynaActionForm and write your own getters and setters.
you would have to make it anyway coz (as far as i know) i couldnt find a better way to do validatoin on indexed values. hence wrote it in the validate() method. > What if I have a DynaAction form . In that case how do I handle the > getter/Setter method ... > > -----Original Message----- > From: Rajat Pandit [mailto:[EMAIL PROTECTED] > Sent: Sunday, December 14, 2003 3:16 PM > To: Struts Users Mailing List > Subject: indexed properties mini(est) HOWTO > > > hello, > am positng a quick HOWTO to get started with using indexed properties, > as i guess almost everyone has had to deal with it atleast once. > > pls post any suggestions/additions etc to improve on it. i might add on > the JSTL version a little version of it.
