A potential success story. Or just a cool thing to look at.
by David Zmick 02 Jul '11

02 Jul '11

I am a high school student and I am going to be a senior this year. College seems pretty competitive these days, so I figured that if I want to get a computer science degree(which I do), it might really help with admissions to have some sort of project I have done to show off. So, my dad and I discussed it and we came up with a project idea. The project is simple: create an extremely user friendly decision matrix style decision analysis tool. Next I whipped out my high school programmer skills and attempted to make this thing. I discovered I don't know nearly as much as I would like to, but I have a functional version of my tool running(hopefully it still is by the time you read this) and I would like you guys to check it out and tell me what you think. So here is my college admission/pretty useful seaside app: http://which-one.org things I know need working on: - enter button needs to work, hitting enter breaks things or does nothing. - I should make focus jump to the text boxes in lightboxes. other than that i have nothing else that I have found wrong, so please please find more things for me to learn from! thanks in advance. -- David Zmick dpzmick(a)gmail.com

Dale It seems that my answer was hidden under a pile of other emails. I actually tried to do what you recommend to use render (Smalltalk at: #ConfigurationOfSeaside30) record to get the load sequence of ConfigurationOfSeaside30-dkh.316 in Squeak 4.3-11481. But it did not work. What am I missing? Regards Hannes ---------- Forwarded message ---------- From: "H.

I was not aware of this logging feature. However it did not work in ftp://ftp.squeak.org/4.3alpha/Squeak4.3alpha-11481.zip If I do "Seaside 3.0 http://www.seaside.st" (Installer ss project: 'MetacelloRepository') install: 'ConfigurationOfSeaside30'. (Smalltalk at: #ConfigurationOfSeaside30) load. (Smalltalk at: #WAPharoServerAdaptorBrowser) open. I get the error message that ConfigurationOfSeaside30 does not understand #record. What am I missing here? Regards Hannes

Is there a way to access the upload progress from the browser? It shows it in the status bar already. RS

Comparison by example
by Janko Mivšek 30 Jun '11

30 Jun '11

Hi guys, I'm opening a new thread with idea by Johan and Hannes to write an example app on all three web frameworks. Here is a copy of that thread and first Hannes proposal: Johan: For comparing, it would be really good to have the same application written in the three frameworks by experts and have the experts compare them. Hey, if I find the time (oeps) I would even love to help out on that one. Janko: Agreed! And I'm hardly waiting for someone to come out with an idea, what to build for such comparison. I have one, but you will for sure declare me biased again .. :) A so called real-time web example: a multi-user chat. As that one on GMail, for instance. Another would be a basic CRUD example, which is so common pattern, filling that 90% of cases, to show, how the frameworks cover the people's most basic needs. Hannes proposal: --------------- Maybe a sample application which is combination of both your suggestions :-). A kind of more elaborate ToDo list (cf. the Seaside example in the tutorial) Features: - Multi-user - The users see a list of ToDo items and sees to whom they are assigned. - In a chat area they can discuss about the items and reassign them accordingly. - Some views/reports (current tasks, my tasks, finished tasks, task in a particular month). If you want more - A wiki in addition - A glossary (special terms in the reports are automatically hyper-linked to a glossary entry) Best regards Hannes P.S. I am sure that other people have better ideas. I have no idea how much time this takes to implement in Aida/Web. In Seaside it is quite an effort. -- Janko Mivšek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

demo/demo works as a test account. And thank you for the feedback, I will see what I can do with escape and enter as soon as possible.

Re: [vwnc] [Seaside] Re: Comparison of Aida/Web, Seaside and Iliad web frameworks
by Runar Jordahl 30 Jun '11

Come on… We all know Janko is biased, and the comparison reflects that. But it is not like he wants to take over the world and kill Seaside. Well… maybe he wants, but there is still no reason to get upset. :-) I have only tried Seaside, choosing that framework since it is the “default” one to use for Smalltalk web development. At least the comparison made me aware of Iliad, and had me rediscover Aida. But even if I now have more knowledge, I am more confused than ever. We need some small reports, from various sources, comparing the strengths and weaknesses of the frameworks. Creating a collaborative to-do-list application might be a good reference case. >From what I understand, all three frameworks generate HTML using roughly the same techniques. But there are differences in how you compose a page from multiple components. The spreadsheet mentions “composition” vs. “rendering”. Getting a short discussion about these concepts is probably more helpful than a lot of (smaller) features compared. It seems like everyone agrees on the importance of JavaScript. So explaining how the various frameworks handle this and how they will tackle it in the future, is important. It seems like Aida and Seaside takes different routes here. How does that matter for me as a user? Again, a more detailed discussion than “yes” / ”no” on a feature list, would be welcome. It is also interesting to see how this thread discusses the future of Smalltalk web frameworks. As I understand this, we have Aida, Iliad and Seaside being the “server-centric” web frameworks. These frameworks generate the UI on the server, and use third-party JavaScript libraries to provide a richer UI experience at the client. Then we have Quicksilver and Jtalk which basically let you run your UI (Smalltalk) code in the client browser itself. These “client-centric” frameworks are experimental and not ready for production. As Janko mentions, integration between these two types of frameworks will be important. Kind regards Runar Jordahl blog.epigent.com

something like #callback:value: but for #html: ?
by Esteban Lorenzano 30 Jun '11

30 Jun '11

Hi, I'm trying to fill an JQAccordion when user opens it, and I think the way to do that is by doing something like this: html div script: ( html jQuery new accordion active: self selectedIndex - 1; autoHeight: false; onChangestart: ((html jQuery new alias: 'ui'; access: 'newContent'; call: 'load' with: (html jQuery ajax html: [ :renderer | renderer text: 'TEST' ]; fullUrl)) asFunction: #(event ui))); with: [ html div id: 'header1'; with: 'header1'. html div. html div id: 'header2'; with: 'header2'. html div ] this example is working fine, but I'm always rendering 'TEST'. I need to discriminate which content I need to render, so I need the header id value. Using #callback:value I would call something like: ((html jQuery ajax callback: [ :v | "Some code here" ] value: (html jQuery new alias: 'ui'; access: 'newHeader'; call: 'attr' with: 'id')) asFunction: #(event ui)) but I don't have nothing similar with #html: . of course, I can call first a callback who sets the "current header", then make an ajax call, but that's not efficient (two calls instead one). so, I would like to have something like #html:value: does anybody knows how can I solve this problem? thanks, Esteban

bringing up WAWelcome from scratch
by merlyn＠stonehenge.com 30 Jun '11

30 Jun '11

I have a Squeak 4.2 trunk image, which I've successfully loaded ConfigurationOfSeaside30 into. I see that it has the friendly WAWelcome package. I want that. I've opened a Seaside Control Panel from the World menu, but I can't seem to get it to start with either Swazoo or Komanche and WAWelcome and the other usual suspects configured. What's the magical sauce to make it work? -- Randal L.

A solution for blocked (locked) updates and the "back" button
by Louis LaBrunda 28 Jun '11

28 Jun '11

Hi Seasiders, I recently asked a question about canceling a request before the values of the form fields are applied to an object and stop them from being applied, so I wouldn't need a copy of the original object. Julian suggested I use a cancelButton, it was exactly what I was looking for at least for cancel buttons (thanks Julian). I then wanted to take things a little farther and cancel updates to objects when the object is locked for some reason or if the user was playing around with the web browser back button. I came up with a solution similar to the cancelButton. I created two subclasses and an extension that I detail below. They allow me to set a hidden value whose callback gets processed before all other value callbacks. The callback is a one argument block that receives the hidden value. The callback can check the hidden value against a saved value to see if the "back" button was used or make other tests to determine if it is okay to apply the form values to whatever objects they are connected to. The callback block returns true if processing should continue and false if not. To stop processing WARenderNotification is signaled. I'm happy with this solution but would like to know if: 1) It really makes sense? I'm not doing anything against Seaside rules. 2) There is a better way? If this seems like a good solution, the Seaside developers are welcome to it. I'm not married to the names of the subclasses or the #earlyHiddenInput method name. It is somewhat short for early-response-hidden-input, so I am open to suggestions. Lou I subclassed #WAHiddenInputTag with: #WAEarlyHiddenInputTag and overrode callback: with: callback: aBlock self name: (self storeCallback: (WAEarlyValueCallback on: aBlock)) where WAEarlyValueCallback is a subclass of #WAValueCallback of which I overrode #evaluateWithArgument: and #priority as follows: evaluateWithArgument: anObject (block valueWithPossibleArguments: (Array with: anObject)) ifFalse: [WARenderNotification signal]. priority ^ -3 To wrap things up I extended #WARenderCanvas with: earlyHiddenInput ^ self brush: WAEarlyHiddenInputTag new ----------------------------------------------------------- Louis LaBrunda Keystone Software Corp.
