Seaside, Omnibase, OmnibaseSupport - markDirty failing
by Wilkes Joiner 28 May '06

28 May '06

I'm learning to use Seaside with Omnibase and am having some issues. I'm getting a "ODBError: Object is not persistent or is a part of composite persistent object" when calling markDirty on an object. Here is the setup for the app. I'm using a custom Session class, BLGSession, which is a subclass of ODBSSession. I have one domain object, BLGPost, and two components. One for listing posts, BLGPostList, and another for creating and editing them, BLGPostEdit. BLGPost inherits from ODBSPersistentObject. It has a body attribute with the following setter: BLGPost>>body: anObject body := anObject. self markDirty. The edit component is causing the problem. When I call it to modify the body attribute of a Post I get the "not persistent" message. BLGPostEdit>>post ^ post isNil ifTrue: [post := BLGPost new] ifFalse: [post] BLGPostEdit>>renderContentOn: html html form: [html paragraph: [html label for: 'post_title'; with: 'Title'. html break. html textInput on: #title of: self post]. html paragraph: [html label for: 'post_body'; with: 'Body'. html break. html textArea on: #body of: self post]. html submitButton callback: [self answer: self post]]. I've tried many variations and permutations of this, but can't seem to get this to work. Anything obvious that I'm missing? Is my approach off? Thanks, Wilkes

Static link to get variables
by Florian Minjat 16 May '06

16 May '06

Hi, I would like to use some Flash to interact with my seaside app. To create the required tags with the chosen params, no problem. But I don't know how to make Flash communicate with Seaside. My primary idea is to have a static link where the flash app could send GET variables to seaside. For example http://localhost:9090/seaside/MyApp/aName?param1=var1&param2=var2 . But I have no idea how to create a static link like this in Seaside nor to compute the get variables. Any idea ? Florian

static image files
by Christian Mascher 22 Apr '06

22 Apr '06

Hello, a question the tutorials didn't help me with: how can I make an image-file show up? I tried this in Counter>>renderContentOn: html image: 'filename.png' but nothing happened. First I thought it was the directory-problem. If I put the image in the same directory as the squeak .image and .exe is an URI with just the filename correct in this case? Then I found in another tutorial, I have to tell WAKom to serve static files as well. So I did this (from the Schaffer-tutorial, with the FileRoot renamed): "Kill all existing Kom HTTP servers" HttpService allInstancesDo: [:each | each stop. each unregister]. "Start a new server on port 9090 servering both static content and seaside apps" | ma seaside | seaside := WAKomEncoded default. ma := ModuleAssembly core. ma serverRoot: (FileDirectory default directoryNamed: 'D:\squeak37') fullName. ma alias: '/seaside' to: [ma addPlug: [:request | seaside process: request]]. ma documentRoot: (FileDirectory default directoryNamed: 'D:\squeak37') fullName. >>BTW: Can I specify other base directories in both cases, or just for >>the documentRoot (static content)? Quite a bit confused here... >>In other words: Why specify a server root, when it is the same with >>FileDirectory default (place of the image) ma directoryIndex: 'index.html index.htm'. ma serveFiles. (HttpService startOn: 9090 named: 'httpd') plug: ma rootModule Now I could go to http://localhost:9090/ and the server would give me a static index.html I put in the directory 'D:\squeak37'. But the image referenced in this file could still not be loaded. So no wonder it didn't work in the seaside-application. Still the image-file is there and I can open it with FileList in squeak, so the format seems OK. Whats going on? Thanks Christian

push-model of interactive web pages
by Jason Rogers 12 Apr '06

12 Apr '06

I just came back from the Real World Ajax Seminar in New York City. The seminar was pretty good in general, but one really neat thing I saw was the innovation of a push model type of live update. The trick is to embed a small (1px by 1px) flash file. This embedded object has the capability of opening a socket to the server. The web page can then register itself to the server over that socket and bada-boom-bada-bing the server can PUSH information to all connected clients. The two demos of this functionality I saw were in the context of Flex programming and Ruby on Rails. The Flex guy showed outlining directions on a map in a browser -- those outlines showed up immediately in the two other browsers that were connected to the server on different sessions. The Ruby on Rails guy showed several examples of adding and deleting records in a web app through various interfaces with the server (browser, commandline, etc.). These adds and deletes showed up immediately in the other browsers that were connected in different sessions. Pretty neat stuff! This is definitely something that could be a big win for Seaside. I will be working on it over the next month to see if I can implement it. However, if someone beats me to the punch: all the better. -- Jason Rogers "Where there is no vision, the people perish..."

My sample Seaside web-app..
by Rick Flower 02 Apr '06

02 Apr '06

Hi all.. Sorry for being such a pest over the last days & weeks with various Seaside/VW issues! Anyway, I thought I'd share with you all, my initial cut at a vanilla web-application that can be used as a starting point for your own web-app or as learning material for anyone new to the Seaside/Smalltalk environment. I'd like to thank Brian Brown for his help with some overall design & layout issues (and remote debugging) as well as to thanks all of you as well! With all of your help, I was able to get this sample site up and going fairly quickly (with my limited time). It's definitely been a learning experience and I'll be fine tuning this code for my real web-application in the coming weeks & months. Anyway, now that my reverse proxy (using Squid) is up and going, I'm all set to have people try out my sample application... My application uses the following features of Seaside/Smalltalk : 1) Seaside - New Canvas API for rendering html objects 2) Glorp - I've got some very rudimentary Glorp code for examination of a user table for logging into the web app. I've not really delved into the depth of features that Glorp offers and will go down this path real soon as part of my other web app task. 3) external CSS & GIF files -- I like using external files for css/gifs since I can offload the Seaside web server from doing that task and leave it for my proxy to do. Keep in mind that this code is not visually very polished in terms of what it presents as that was not the main focal point of the exercise.. You can hit the links at the top of the pages and it will just render a line or two of text showing how the links are put together (once you see the code anyway), etc.. The site allows logins using the "demo" user and demo password which talks to a PostgreSQL database behind the scenes using Glorp. Anyway, I now need to upload the package to the Cincom repository I guess (or is there some better place to put it?). Anyway, here's the weblink -- and please let me know if you have problems with it: http://seaside-demo.ca-flower.com -- Rick

Hello, I just published Seaside 2.6b1.8.0 on the public Store repository. This is the result of porting Seaside2.6b1-mb.8.mcz which also includes everything from the 2.6a3 branch, up to Seaside2.6a3-lr.51.mcz. At the same time, I published the first version of SeasideScriptaculous for VW and a new version of SeasideAsync. Please feel free to report any bug that I could have created during the port. And enjoy, Michel.

WAStateRegistry objects keeps getting bigger
by William Harford 02 Apr '06

02 Apr '06

Hi all, WAStateRegistry objects keeps getting bigger. Is that right? In busy sessions objects grows to 5,000 6,000 +.How big does the typical WAStateRegistry objects get? I am a little stumped as to why it is getting so big. I would of thought it would be something like (Number of components on a page) * 20 . What am I missing? Thanks Will

Seaside on ST/X ?
by Andreas Brodbeck 31 Mar '06

31 Mar '06

Hi all I noticed that on the current Smalltalk ST/X version, there is Seaside 2.5b4 included! That really surprised me! (ST/X is available here: www.exept.de) I did not try it yet, though. Has anyone some more information on that seaside port to ST/X? Who is maintaining it? How does it perform on ST/X? On the official seaside website, there is a note, which says, that seaside on ST/X is not possible. Maybe some preconditions changed with the current ST/X version, so it is possible now? Thanks for any information! Andreas -- *** Neues von mindclue *** www.infodaktik.ch www.scratch.ch ······································· mindclue gmbh Andreas Brodbeck, Geschäftsführer Dipl.

RE: [Seaside] Bug in in SUFormTest>>renderLabel:control:model:on:
by Bany, Michel 31 Mar '06

Scriptaculous is primarily targeted for 2.6a3. On the other hand, the latest versions of SeasideAsync require 2.6b1. I am currently attempting to integrate all these pieces and to make everything portable to VW. See Seaside2.6b1-mb.8.mcz You may want to try that. If you do I'll be happy to hear your feedback. Enjoy, Michel. ________________________________ From: seaside-bounces(a)lists.squeakfoundation.org [mailto:seaside-bounces@lists.squeakfoundation.org] On Behalf Of Gaetan Le Brun Sent: Friday, March 31, 2006 2:55 PM To: seaside(a)lists.squeakfoundation.org Subject: [Seaside] Bug in in SUFormTest>>renderLabel:control:model:on: Hello, So I downloaded the following packages on SqueakSource : Seaside2.6b1-mb1.6.mcz SeasideAsync-mb.33.mcz Scriptaculous-lr.47.mcz I tried the scriptaculous demo (SUAllTests) and when I selected the Form link an error occured.
