Thanks guys, Like I said in the initial post: I am doing this on the client side, because I have to.
Doing it on the clientside involves jumping through some hoops. Namely, inject the component to get its id and then add some javascript to the page using RenderSupport. No problem. It iss done... but I am just wondering aloud on the list why I need to jump through the hoops. Why tapestry 5 has this feature that costs me a lot to circumvent and benefits me very little? I'd just like to know in what cases there is a benefit to this behavior so that I don't feel like I am being made to suffer (just like I used to in struts) Cheers Russell -----Original Message----- From: Kristian Marinkovic [mailto:[EMAIL PROTECTED] Sent: Tue 9/30/2008 2:55 PM To: Tapestry users Subject: Re: T5: t:select how to disable and re-enable it is not enough to enable the select box only on the client site. because if you render a select component with disabled="true" tapestry wont even "register" the necessary event handler to process the submission. in tapestry 5 words: no ProcessSubmission component event will be serialized into the form thus no values will be processed. :) (see Select->AbstractField component source code) i see two possibilities: as mentiond by andy do everything on the client side or do a ajax request (zone) updatind the select component with disabled="false". g, kris Andy Pahne <[EMAIL PROTECTED]> 30.09.2008 15:45 Bitte antworten an "Tapestry users" <users@tapestry.apache.org> An Tapestry users <users@tapestry.apache.org> Kopie Thema Re: T5: t:select how to disable and re-enable Maybe it's possible that you disable your select only clientside? If you do so there won't be any problems if you later on enable it again. Andy Russell Brown schrieb: > Hi, > I am using a T5 select component. When the form renders I wish the select to be disabled so I use disabled="true" parameter. However, some javascript causes the field to become enabled. If this happens however the value selected does not get sent into the property of the component. I am assuming this is thanks to the "feature" decribed here http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Select.html thussly : > > "If true, then the field will render out with a disabled attribute (to turn off client-side behavior).
