onComplete: and later

Norbert Hartl — 2008-07-24T07:38:50

In the method comment of SUAjax>>onComplete: there is "possible automatic behaviors" mentioned. What does that mean? I'm trying to execute a piece of javascript code after a updater request has been sent, the returned element has been included in the DOM and returned scripts are executed. Is there any chance to do this or what would be good approach? What I'm trying to achieve is that in an updater callback an element is rendered and a piece of javascript which creates a new object. After the updater return is received and the element is hooked in the DOM and the code created the object I like to trigger a function that registers them both at global object. thanks in advance, Norbert

Back button question

itsme213 — 2008-07-23T22:43:45

Most interaction in my app is Ajax based. Due to some Seaside 2.8 restrictions I am using Lukas' #in:do: workaround for updating/re-rendering one component from the callback of another. This seems to cause the callback count to increase with time (at least the little callback numbers in Seaside generated links keep increasing) _s=i178duf&_k=usj27a&45 <- 45 OK, so I sometimes do an explicit whole-page refresh html anchor callback: [WARenderLoop new call: self] with: 'Explicit Refresh' This of course enables the back button, presumably keeping around stuff that is meaningless for my application. I'm hoping for a simple way to free up at least some of the resources (e.g. large number of callbacks? some RenderContinuations/Contexts/or similar?) left around to support the back button. Is anything like isolate: applicable? html anchor callback: [self isolate: [WARenderLoop new call: self]] with: 'Explicit Refresh' Other suggestions? Thanks - Sophie

with: takes block vs string

SainTiss — 2008-07-23T11:31:16

Hi all, I might be missing something here, but it's confusing to see that the with: message sometimes expects a string, and sometimes a block, depending on which tag/brush the message is sent to. For example, html script with: expects a string, while html div with: expects a block. What's the rationale behind this? Thanks, Hans

javascript function with seaside callback [Fwd:generating a script containing html]

Seaside Security

Hans N Beck — 2008-07-23T04:46:46

Hi dear Seaside gurus :-), one think I never really understand using Seaside: by default, there is this control bar at the bottom "configure toggle halos new session etc". Whow can I make sure that only an special logged-in user can see this bar ? I have read about and played with WAAuthConfiguration, but neither it could let disappear the bar nor I got any log-in window (or could see if I maybe already be logged- in). How to do this ? If I manage User and Groups in Pier, are this the same as for WAAuthConfiguration or are these user managements completley divided ? Thanks for help :-) Hans

Bug? calling javascript function from onComplete:

Norbert Hartl — 2008-07-22T12:21:33

I need to chain some calls I do with Ajax. I found the onComplete:, onSuccess: etc. handlers. Every example I've found in the image uses them to invoke an html updater. Trying to do this ... onClick: ( html updater callback: []; onComplete: 'alert("booo!");' ); with: 'something'. leads to javascript code like new Ajax.Updater('layers','http://localhost:9090/seaside/svgex',{'insertion':Insertion.Bottom,'onSuccess':function(){'alert("boo!");'},'evalScripts':true,'parameters':['_s=EagyxUvvWRPxlAdD','_k=K3OXE7pw','4'].join('&')}) The problem is that to javascript code is printed with surrounding ticks ' and therefor cannot be executed. Am I doing something wrong or should be work that way? thanks, Norbert

SainTiss — 2008-07-21T19:43:04

This does not seem to work... For some reason, it insists on saving to the local package cache, of which the path in the remote image indeed does not seem to have been changed... Any way to force it to update its path?

Apparently, the problem occurs when Monticello in the remote image tries to *store* the mcz locally. The repository path must be included in the mcz file somehow. This means I can probably solve it by using an FTP repository or something... Hans On Monday 21 July 2008, Lukas Renggli wrote:

Hey, first, I am a Squeak/Smalltalk newcomer, so please forgive me if I make an obvious error. I also give as much detail as I can and would greatly appreciate general comments. I am trying to write a small survey application, for that I created a class WASurvey: WAComponent subclass: #WASurvey instanceVariableNames: 'survey questionsPerPage currentPage' classVariableNames: '' poolDictionaries: '' category: 'questionaire' survey is a list of questions, questionsPerPage/currentPage should be obvious.

Help wanted with a small Seaside e-commerce application

Matthias Berth — 2008-07-18T15:37:54

Hello, I am looking for a consultant (or a student wanting a nice summer job) to help me get a small e-commerce application from the current prototype stage to launch. The application is based on Seaside and Pier, major missing features are: - credit card processing (should be done via an external provider) - customer billing information - persistence (something like SandstoneDB should be enough) - invitations (users inviting other users) - recording of transactions (sending an email and putting an entry into a log when someone buys something) - various deployment issues (squeak on linux), like backup at regular intervals, communicating via http with another process. The system currently has around 60 classes of which 16 are unit tests or Albatross tests. The system will be launched in stages, e.g. invitations won't be there initially. I am willing to let you publish non-proprietary parts of this as open source. For example, a good packaged solution for credit card processing (maybe based on code from R

Draggables and triggerPassenger:

Karsten — 2008-07-17T15:32:33

Hi list, I just tried to use triggerPassenger: in an onDrag event. The problem is that Firebug sais that argument[0].id is undefined and thus stops executing the script. Is that a bug or did I miss something? The code that I tried is: (html div) passenger:5; script: (html draggable onDrag: (html evaluator triggerPassenger:[:obj | obj halt])); style:'width:50px;height:50px;background-color:red'.

OSCON "contest"

Kyle Dawkins — 2008-07-16T21:46:58

Hey Seasiders The RoR folks are running this at OSCON: http://pdxfoscon.org/competition Probably a good opportunity to show-off what Seaside can do. I can't attend so I can't volunteer but presumably since they mention Seaside and Gemstone, there are some people already signed up in the Seaside camp? Yes, yes, it's a silly contest (and proves very little), but could result in a few heads turned in our direction, no? I'd love to watch this... hopefully someone will provide a screencast at some point?! Cheers Kyle kyle< at >idealist.org

Seaside/Squeak/Linux: service with GUI as needed

Bill Schwab — 2008-07-15T22:42:35

Lukas, I certainly did not intentionally ignore OB. However, it was easy to do :) Knowing there was more to see, I did some searching. Even with the pre-built image, the Seaside-driven part was a hassle to get working, leaves a somewhat cumbersome setup of the server and web browser running together, and (just my experience, however unfair) appears to not work very well, for whatever reason. No doubt, one would run the image headless, and smooth over the rest of the installation. Still, it is a lot more complicated than the Pinesoft approach of slapping pixels on the screen, and probably more complicated than using wxWidgets, or whatever they call it now. I am not particularly worried about a native widget interface. My experience is that users will tolerate almost any non-ugly look, but are VERY fussy about feel. The latter gets to "muscle memory," intuitive design, and consistency of interaction. Thanks for the insights into Seaside configuration! Bill ========================== Lukas Renggl

Seaside/Squeak/Linux: service with GUI as needed

Bill Schwab — 2008-07-15T14:00:15

Lukas, With respect to "plug it in and throw the switch," you mention that it is possible. Are there any tricks to it, other than setting up the Squeak/Pharo image as a service? Are the following links worthy of attention? http://onsmalltalk.com/programming/smalltalk/seaside/my-journey-to-linux/ http://onsmalltalk.com/programming/smalltalk/scaling-seaside-redux-enter-the-penguin/ Re configuration, most of it would be things that I would do through Seaside. The exact details (Seaside served from "the" image doing the work, or a Seaside image along side of other images doing the real work) will depend on my experience with reliability. I have read widely differing reports on what to expect, and need to try it. My BibTeX gizmo looks like it will be the sentinel. OmniBrowser is prominent in your reply. What feature(s) of it earn that position? RemoteFrameBuffer looks like it could be very useful, though it appears to encrypt only for password exchange. Do you have any concerns about its security

thoughts on Seaside 3.0

Jared Hirsch — 2008-07-14T17:10:26

I've been lurking in the squeak/seaside lists for a while, and feel I should add to the discussion of new features for a possible seaside 3.0. The major obstacle that I see to further adoption and growth of seaside is widespread community ignorance of the design side of web development. This has to do with templates, but it runs much, much deeper. The html templates issue has two sides. From a design standpoint, burying html inside smalltalk leads to opposite but equal maintainability problems and inelegant html code. The reality of the web is that good graphic designers create XHTML by hand, and giving good designers control only of the CSS (like in seaside 2.8) isn't nearly enough. I think everyone should spend an afternoon reading articles on 'a list apart' to start to understand that there are intelligent people who devote lots of time to hand-coding "beautiful html." And take a look at the design openings on 'authentic jobs' to see that there are web design companies that pay lots of money for this
