Using updater without triggering action callback?

Say you have a form with default action callback to run a search. One of
the criteria for this search is specified using a select list in that form. Now I'd like to attach an updater to the select list to populate a little "extras" div to the side of it with selection details, but I would like to do so without triggering the default action of a form that would actually execute the search? (html select) list: self accounts; labels: [:acc | acc name]; selected: self account; callback: [:value | self account: value]; onChange: ((html updater) id: divid; triggerForm: formid; callback: [:r | r span: self account name]) (html div) id: divid; with: [].

Also, to see exactly what I'm talking about, just add (defaultAction:
[]) to the form in SUFormTest>>renderLabel:control:model:on: then play with examples, specifically select list, but all others exhibit the same behavior.

It almost seems that if we used a different kind of callback for that
"default" submit button on a form and ignored it during the callback processing when isXmlHttpRequest = true that might fix it, although now we've got to think if this is ever desirable, and so far (given the ugliness of the result) I can't think of any cases when this might be so.

why not just seperate selection and text input into two seperate forms?

Simply because search criteria form includes a number of fields and
submitting half of it would do no good for actually executing a search with only half the query parameters set later on. Or say you only have a single select list + button on a form, and you'd like it to have default action. This is a bug IMHO, not a feature.

The easiest solution for your problem would be to write in your default action block something like: self session currentRequest isXmlHttpRequest ifFalse: [ " default action code " ] I am not really sure if we want this as a default. There are several problem serializing hidden-fields, buttons and some of the "composed form elements" like checkboxes and multi-select lists (some of these problems have been fixed in 2.8). Maybe you could also trigger in your drop-down just the relevant form elements using a cascade of #triggerFormElement:. Note this also works for multiple forms, etc. Lukas -- Lukas Renggli http://www.lukas-renggli.ch _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Lukas,
That was my first reaction as well and I did try to suppressing the callback from the inside, however it's really the render notification signal that immediately follows that will screw things up even if I don't actually do anything in the callback itself as demonstrated by my later suggestion of adding an empty callback to SUFormTest to be able to see the mayhem. It seems there should be a general solution to this and the more I think about it the more I lean towards trying to suppress execution of that single callback altogether to see if that fixes the problem but I can't think of a clean way of tagging it as such quite yet.

I am sorry, I was probably reading your mail not careful enough ... Fact is that I changed the way and order in which callbacks are evaluated a few weeks ago after that discussion about the handing of submit buttons and AJAX form serialization. It seems that these fixes also solve your problem and does not even require a test for #isXmlHttpRequest. So I suggest that you update to the latest version of Seaside 2.8 and Scriptaculous.

Ah, cool, I will give them a try when Michel gets a chance to push the latest to visualworks, I'm not sure what version I am at currently. _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Thanks, I'm on 426 at the moment, which is the latest in Public
Repository. /me pokes Michel and Michael to find out how far along they may be on the path of automatic ports being made available to VisualWorks users like myself ;) Thanks! -Boris -- +1.604.689.0322 DeepCove Labs Ltd. 4th floor 595 Howe Street Vancouver, Canada V6C 2T5 http://tinyurl.com/r7uw4 [hidden email] CONFIDENTIALITY NOTICE This email is intended only for the persons named in the message header.
