To really do something like this properly you'd probably have to mess around with the internal implementations of FormSupport / AbstractFormComponent in order to skip over rewinding of form components that you don't want validated / values parsed from.
This also starts to slide into the world of direct rendering / etc. Not an easy thing to do currently. I plan on implementing this in 4.1, but will probably save it for last as I'm assuming I'll need lots of time to play as it'll probably be as hard to implement as adding the new render cycle was. (Not that it was hard to do because of tapestry, just hard to do in a clean / intuitive / non-breaking way that makes sense for the API . ) On 7/8/06, Brian Duchek <[EMAIL PROTECTED]> wrote:
I believe that you need to keep the logic for determining if only B should be updated in your submission listener, and use a hidden field/component to track the values last sent to the client. So if the user updates A + B, but only wants to store changes to B... You send everything back to the server, decide to only truly "keep" the change to B, and then scrape the original value for A from the hidden component and overwrite whatever value for A was updated in the rewind of the formm. This is probably clear as mud, because I'm wrestling with the same issues right now in my application and am having issues. Maybe someone on the list can help us determine if my recommendation has any merit or any major flaws. </bd> ________________________________ From: Theo vN [mailto:[EMAIL PROTECTED] Sent: Sat 7/8/2006 2:35 AM To: Tapestry users Subject: Re: Re: RE: RE: Re: Partial form submit Another possibility would be for the form processing cycle only to receive updated values for the parts specified - "old" values for fields A and C and "new"/updated values for field B?
