small seaside image
by Avi Bryant 25 May '07

25 May '07

A while ago I mentioned on this list a stripped 3.7-based Seaside image that was around 7.5MB. A couple of people have emailed me offlist asking for it, and I've finally gotten around to actually putting one up somewhere. You can grab it from: http://smallthought.com/avi/Seaside2.6.zip This includes Scriptaculous and is up to, I think, around 7.8MB now. Let me know if there are any problems getting or using it. Avi

Swazoo versions
by Esteban A. Maringolo 02 Nov '06

02 Nov '06

Hi, Today I was playing with the published version of Seaside made by Avi Bryant the last week, which uses the Swazoo version for Dolphin made by Sean Malloy, to add some missing functionalities I had working in my earlier port of Seaside to Dolphin. Considering to what Sean says in his website, the port is based on the 0.9.101 version, while Steve Waring's one is based on 0.9.99 (apparently). Sean's version is more conscise in terms of number of packages, but it misses some classes such as SwazooSiteScript and other very useful tools, available in Steve's version. Considering that the Swazoo topic got warm this days, and that today it's more a jungle than a zoo ;-), we could arrange some efforts to make it converge into a single stream of development, at least compatible with what already exists in Dolphin. For example, you can't have Seaside and Spray web services running on the same image, because they're incompatible (besides the fact that the naming convention of Steve is different to the Sean's one*). Plus, Dolphin ships with Steve's version, which is appropriate considering the existing goodies and packages available, but not the best option aiming to a broader audience through Seaside and other popular developments that would come. I leave the topic here, to see if there is enough interest to make it happen. I would like to see Sean, Steve, Janko, the OA people, perhaps Bruce Badger too, and anybody willing to collaborate at least in testing, joining efforts for this. Best regards, -- Esteban. * Steve: I will be happy to know what SW, SV, and other prefixes mean. :-) ps: this is a cross-post to c.l.s.d, Swazoo and Seaside mailing lists, sorry for any inconvenience caused.

liveCallback for textarea
by Martin J. Laubach 08 Sep '06

08 Sep '06

Is there a special reason why WATextAreaTag does not implement the liveCallback stuff? I just copied the method over from WATextInput and it works fine. I can see that pasting tons of text into the textarea might not be a good idea, but in I see no problem in principle. mjl

WAComponent
by Ramon Leon 05 Sep '06

05 Sep '06

Lucas, I fired up Pier last night after having not touched it in a while, went to do a small project and none of my components worked anymore, couldn't configure their settings. Turned out seaside's WAComponent now includes an accessor on the class side called description, which returns the class name, and overrides what Magritte expects to be a description builder. Have you noticed this or are you working mostly in 3.9 with pragma's and not using the older builders? I also had quite a few issues just loading the latest versions from your repository, kept getting warnings from Monticello about it not being able to find a previous version, yet the version was right there. Comments?

[FW] Seaside,Scriptaculous and Forms...
by Cédrick Béler 04 Sep '06

04 Sep '06

Hi all :) Using seaside need sometimes some prerequesites with Html... especially with forms - First rule I wasn't aware is that it's not possible to nest forms which can be tempting sometimes... This is a HTML limitation which can result in browser being confused and then in impredictable behavior. - Second rule, all form inputs have to be inside a form tag to be submitted to the server... Actually, it has to, because with scriptaculous form element's generally don't need to be within a form to submit I had a discussion with Lukas yesterday (list down) about that last point as I didn't know if it was good to use form inputs alone... Lukas said yes to me and gave me some more information about forms in scriptaculous Here are the important points of the discussion: -------- Is it possible to use certain form elements without forms in scriptaculous ? -------- It's possible for: text-input, password input, submit buttons, single select lists, option buttons (All single value submitted) and then you have to use #triggerFormElement: to serialize the state It's not possible for multi-selection inputs like checkboxes and multi-select lists because #triggerFormElement: does not work for them. The solution here is to add a form and submit the whole thing for those elements using #triggerForm: instead -------- Why this is not possible ? -------- This has to do with some magic seaside is doing ;) and which is not really compatible the way scriptaculous works. Seaside uses additional hidden fields for checkboxes and multi-select lists that don't get triggered properly by scriptaculous (it only triggers the single field you specify). The extra hidden fields are needed by seaside to evaluate the callbacks properly to make it so conveniant. -------- How to push something to the server without redrawing? (direct acces to the model in the image without any validation) -------- SUAjax SURequest #() SUEvaluator #() SUUpdater #('id') SUAutocompleter #('element') SUInPlaceEditor #() SUPeriodical #() -------- request (SURequest) just posts a request and submits data ... onChanged: (html request triggerForm: 'bla') -- updater posts a request, submits data *and* updates some content (used in SUClassBrowser to update dynamically the content of the code browser of the scriptaculous demo) -- evaluator is used to request and inject a javascript into the existing page () -- Here it is ;) Hope that helps other people..

[Newbie] Confused about #registerAsApplication
by Bakki Kudva 03 Sep '06

03 Sep '06

Hi, I have been reading that a new app which is subclassed from WAComponent should be registered like MyComponent registerAsApplication: 'foo'. However when I see the examples like the Store or the Scriptaculous SUAllTests apps I don't see this in their initialize methods(or anywhere else in their components). Is this automatically done for every subclass of WAComponent so it shows up in seaside/config? Thanks for your help, bakki

Magma on seasidehosting
by Pablo Iaria 01 Sep '06

Hi all, I'm trying to deploy a small seaside+magma application on seasidehosting.st. First I made a small application to create the repository, then I added a WAMagmaConfiguration and set up the repository absolute path suggested to /service/edp/files/edp_messages and I got the following stacktrace.

Object Instances / Garbage collection
by Dmitri Zagidulin 31 Aug '06

31 Aug '06

I suspect this might be a general Squeak question, but I want to ask it here in case Seaside adds some complications or things to consider: How do I delete object instances (is forcing garbage collection involved) from the image? So, for instance, say I have a simple Shopping Cart and Items sort of setup. I add several Items to the cart, which creates instances of those objects. And then I want to remove them from the cart, delete them. But they're still around in the image, inspecting Item allInstances still reveals those items which are no longer in the cart. This sort of thing happens all the time in my web apps (I'm using the simplest form of persistence - in image, no database or anything, while prototyping), and I'm wondering how you guys get around that. ~Dmitri

question about avi quote
by Dustin Lee 31 Aug '06

31 Aug '06

I saw Avi speak at OSCON and have been working on a test migration of a python/quixote/sqlobject application as I find time. I'm very excited about seaside so far. During his talk he gave a quote that I can't remember who it was by or in what context but I thought someone on this list might know. The quote was something to the effect: "The history of programming has been from global state to local state" (or something like that). I believe he mentioned this when talking about how the use of codeblocks and other seaside-isms make it so you don't even need to give names to many things. If this quote rings a bell for any one I'd be interested to learn more about the concept/context. -- Dustin Lee qhfgva=rot13(dustin)
