Re: Guiding the Albatross to the VW-Seaside? [was: [Seaside]Seasidefor VisualWorks]

I would hope so seeing as that's where majority of development is happening right now and cincom focus will first be on better integration and only then on seaside itself if I understand correctly.

Seaside sessions and ajax
by sig 06 Dec '07

06 Dec '07

Hello there, i having few questions about how seaside handling ajax update requests. I found that it handles differently, not like a regular page navigation. For instance - continuation is not changing. And i have a problem with sessions: when session expires, by default we redirect page to show login page. But with ajax its just returns an empty result, rendering updated page parts empty. How i can handle session expiration with ajax correctly? Also, i would like to make continuations updating for ajax, so any user action regardless ajaxed or not with have new continuation id. How this can be done? Regard, Igor

i10n or speed?
by Philippe Marschall 05 Oct '07

05 Oct '07

Hi Have you ever tried a counter in a recent version of Seaside? I don't know about you but for such a simple application it is way too slow for my taste. As part of the 2.8 cycle we look into ways of making Seaside faster. Attached you will find several traces for the counter application. As you can see, an awful lot of time is spent to convert URLs to String. Of that most time is spent in#encodeForHTTP. So what do you find more important, that Seaside is fast or that is supports non-ascii urls? Cheers Philippe

[ANN] ShoreComponents 3 - back on Seaside
by Pavel Krivanek 17 Aug '07

17 Aug '07

Hi all, till now ShoreComponents used some special technological properties that helped to solve some general problems of Seaside applications. Unfortunatelly this properties cased that it was not easy to use ShoreComponents with standard Seaside applications. It was possible to use Seaside components in applications based on ShoreComponents but it was almost impossible to use components from ShoreComponents package as supplement of other components. So it was not possible to use it for cooperation with Magritte etc. The third major version of ShoreComponents makes big step in this area and I hope that it will be better and better. Main properies of the next release: - there's no base component class. Components are now based on standard WAComponent - components doesn't require parent reference. They can be created with classical "new" constructor - dynamic variables are used for navigation in hierarchy of components (for specification of target component etc.) - static files are now provided by standard FileLibrary This is the first alpha version so it's far from perfect. The main problem are some form processing issues so some components are not working well. Also nested forms problem is not solved now. Only platform independent part of ShoreComponents is converted now. I hope that you will find it useful and you will find motivation to improve and extend this set of components and use it in your applications. download: http://www.squeaksource.com/ShoreComponents/ -- Pavel

Oddness with #lightbox: in VW
by Yann Monclair 22 Jul '07

22 Jul '07

Hi all, I've been playing around with Scriptaculous in VisualWorks, creating a sample application as a demo for co-workers. During the ajax-ication of my application, I came to use #lightbox: instead of #call: Now this lead to an error in my page rendering ( a MNU) and after investigation I found out that, when you do r:=self lightbox: (aComponent). r will first have for value self , then when aComponent will answer, it will have for value the object answered by aComponent. This is not the same behaviour as #lightbox: in Squeak! So I suspect it is a VW problem. I put together a quick test case app, to reproduce the bug. (attached) Component1 calls component2. everytime it does a call (with #call: or #lightbox: ) it inspects the value or r. As you will see, with #call:, r is inspected only once, and has the proper value. With #lightbox: r is inspected twice, first holding self , then holding the proper value. I will try to look into the problem myself, but any help is appreciated :) Thanks, Yann Monclair PS: for the lucky people coming to Smalltalk Solutions 2007, I'll see you in Toronto!

Charting and PDF export
by Tomas Carini 18 Jul '07

18 Jul '07

I would like to program a reporting tool. Seaside seems great to handle all the web stuff, but I'll need charting and exporting to xls and pdf. What are the options to achieve this wiht Squeak? It would be much better with VW?

Dynamically placing components on a page
by Petr 18 Jul '07

18 Jul '07

Hello Seasiders, I am working on an application, where the user should have the possibility to add and remove components from the page at runtime. More or less it should be a wiki, where each page can contain not only text, but also WAComponents, which the user can place into the page using some XML tags. The closest similar application is the google's personalized homepage (http://google.com/ig). The user is supposed to click on a link on the page and the edit a XML code which contains the description of the content of the page and then just save it. I parse the content of the XML and generate the page accordingly. My problem is when the page is edited and newly rendered, I overwrite the array returned by MyPage >> #children with the list of the new components, which is probably not what I am supposed to do, because when I do this, calling other components doesn't work (any link which is supposed to call another component just doesn't do anything). So my question: Is there a way how the user can add/remove components on a page at dynamically without breaking anything? Bye Petr

Seaside text/plain output problems
by David Goehrig 06 Jul '07

06 Jul '07

Hi everybody! I'm working on a project using Seaside for the first time, and for various reasons it needs to output Content-Type: "text/plain" documents. So having no idea, how Seaside's internals work I started sticking in random 'self break' statements, until I found a place that the Content-Type was set. What I did so far was: WAHtmlRoot<<contentType ^ mimeType ifNil: ['text/html'] ifNotNil: [mimeType] WAHtmlRoot<<mimeType ^ mimeType WAHtmlRoot<<mimeType: aString ^ mimeType := aString This at least allows me to change what was previously a hardcoded content type, but it wasn't enough to allow access from the viewer as I couldn't find an obvious way to access the response object through the html one so: WAHtmlDocument<<response ^response WAHtmlDocument<<response: aResponse ^response := aResponse WARender<<buildResponse | response document | self updateUrl: url. context actionUrl: url. response := self newResponse. response headerAt: 'Cache-Control' put: 'No-cache'. document := self session outputDocumentClass root: self buildDocRoot. document stream: response stream. * document response: response.* context document: document. root decorationChainDo: [:ea | ea renderWithContext: context]. self writeOnLoadOn: document. document close. ^ response At this point I could now alter the response within my View class: TestView<<renderContentOn: html html context document response contentType: 'text/plain'. html text: 'Testing 1 2 3' Generates a page of type 'text/plain' but the page is just the javascript load preamble: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"><head><title>Seaside</title><meta content="text/html; charset=utf-8" http-equiv="Content-Type" /><link type="text/css" href="/seaside/files/WAStandardFiles/basics.css" rel="stylesheet" /><link type="text/css" href="/seaside/files/WAStandardFiles/kalseyTabs.css" rel="stylesheet" /><link type="text/css" href="/seaside/files/WAStandardFiles/sourceStyle.css" rel="stylesheet" /><script type="text/javascript" src="/seaside/files/WAStandardFiles/externalAnchors.js"></script><script type="text/javascript" src="/seaside/files/WAStandardFiles/misc.js"></script><script type="text/javascript" src="/seaside/files/WAStandardFiles/shortcuts.js"></script><link type="text/css" href="/seaside/Test?_s=UbxOBKHRLUulbtSV" rel="stylesheet" /></head><body onkeydown="onKeyDown(event)" onload="onLoad()"><div id="frameContent">testing 1 2 3</div><div> </div><p></p><div id="toolbar"><a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&1">New Session</a> <a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&2">Configure</a> <a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&3">Toggle Halos</a> <a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&4">Spot Profiler</a> <a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&5">Memory</a> <a href="?_k=zekhIJre&_s=VkiqJeuwtxwWVIAM&6">Profiler</a> <a href="http://localhost:3900/seaside/Test?terminate=1&_s=VkiqJeuwtxwWVIAM&…">Terminate</a> <a title="Validate XHTML" href="http://validator.w3.org/check/referer">XHTML</a> <span title="Render Time">0</span>/<span title="Callback Time">0</span> ms</div><script type="text/javascript">/*<![CDATA[*/function onLoad(){}/*]]>*/</script></body></html> So my question is how do I override this! I noticed that I can override the response stream in my View object, but there's a continuation which gets called which will overwrite whatever I put in the stream. Am I going about this totally the wrong way? Dave

How to Implement a Website
by Richard K Eng II 02 Jul '07

02 Jul '07

Hi. I'm a Seaside/Smalltalk newbie. I've studied a number of tutorials and I've read quite a few blogs about Seaside. But I am still puzzled about how to implement a traditional website consisting of a number of webpages that are linked together (eg, homepage linked to "about us", homepage linked to "products", homepage linked to "contact us", etc.). You navigate these webpages by clicking on the various menu selections. But how do you implement that in Seaside? Do you create a component for each webpage with its own renderContentOn: message? If so, how do you invoke a webpage component when you click on one of the menu anchors (eg, html anchor callback: [???] with: 'about us'.). Is this even the correct approach using Seaside? Please forgive my newbie ignorance. Thanks, Richard
