I have both cases. Some of my forms are outside the iterator, others inside. The common factor is that each iteration produces its own <nested:submit> tag. I have lists of things. Each thing has a button that lets the user edit that particular thing.
Am I missing an obvious pattern here? Surely lots of struts web apps do this sort of thing. -----Original Message----- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 06, 2004 9:58 AM To: Struts Users Mailing List Subject: Re: Question about logic:iterator, indexId and hidden fields Actually you might need a name attribute on that hidden field as well ... which could get complicated.
