Yeah, I was afraid of something like that. :) Could you try replacing the two String arrays with two ArrayLists that contain your String objects? That should be pretty easy, just change the method signature in your Action, iterate through the array you already have to create the ArrayList, and return it. You won't need to change the JSP. Might work, might not.
This is really the blind leading the blind at this point though...anybody else got a good handle on populating indexed properties from a form? An array or a Collection? peace, Joe P.S. You might try searching the mail archives for "indexed properties" or "populating indexed properties", I'm pretty sure this has come up before. > -----Original Message----- > From: Rea, Ron [mailto:[EMAIL PROTECTED]] > Sent: Friday, September 27, 2002 2:28 PM > To: 'Struts Users Mailing List' > Subject: RE: Iterate tag question > > > Joe, > > This allllmmmoooost works.
