Greetings All, Is there any way to get the remoteAddress from within a Seaside component? I am trying to log the ip addresses of users of my application. Thanks, Frank

Frozen Image
by Zulq Alam 14 Apr '06

14 Apr '06

Hi, Maybe you can help me, I have an image that is stuck in some form of infinite loop. I can interrupt the loop using Alt+. and a debugger appears but the loop seems to resume again. Any ideas what's going on? Or failing that, what's the best way of recovering code from a .changes file or an external .image file? Thanks, Zulq.

[ANN] Seaside Tutorial in Bern
by Lukas Renggli 14 Apr '06

14 Apr '06

As part of the Smalltalk lecture of Prof. Dr. Oscar Nierstrasz at the University of Bern I will be giving a complete Tutorial for Seaside newbies. Everybody is kindly invited to join all or part this Seaside Tutorial: http://www.iam.unibe.ch/~scg/Teaching/Smalltalk/index.html The preliminary program is the following: * Friday, 5th May 2006, 10:00 - 13:00 Introduction Getting Started Development Tools Control Flow * Friday, 12th May 2006, 12:00 - 13:00 Components: rendering (new canvas api), callbacks * Friday, 19th May 2006, 12:00 - 13:00 Composition: backtracking, subcomponents, widgets, magritte, decorations It is also planned to talk about AJAX (script.aculo.us) sometime, but I don't know yet where this fits in the best. I'll post any changes to the program to this thread. Could anybody planning to attend the tutorial contact me privately by e-mail telling what part(s) they plan to attend so that I can prepare lecture notes and help them to find the location. See you in Bern! Cheers, Lukas Renggli -- Lukas Renggli http://www.lukas-renggli.ch

Uploading Files with Canvas
by Rick Zaccone 13 Apr '06

13 Apr '06

About a year ago, David Shaffer posted an example that shows how to upload a file <http://article.gmane.org/ gmane.comp.lang.smalltalk.squeak.seaside/2587/>. Here is his renderContentOn: method. renderContentOn: html html attributeAt: 'enctype' put: 'multipart/form-data'. html form: [html fileUploadWithValue: self lastFilenameOrEmptyString callback: [:f | self fileSent: f]. html submitButtonWithText: 'Send file'] I am playing with getting this to work with canvas. Here is what I have: renderContentOn: html html form attributeAt: 'enctype' put: 'multipart/form-data'; with: [html fileUpload value: self lastFilenameOrEmptyString; callback: [:f | self fileSent: f]. html submitButton text: 'Send file'] This allows me to select a file, but when I press the Send file button, I get a message saying "That page has expired". Does anyone know what's wrong? I've attached the source code to this message. Rick

Ah, my bad, I thought it was going to be standard, not just an option.

Any time you use a block in a loop, and store a reference to :each, you'll need to fixTemps, very common thing to keep in mind. But callback: doesn't always need fixTemps, only when it's used in this particular scenario. 3.9 should have full block closures so this shouldn't be a problem in the future.

In this scenario, ea is actually a method level variable. Blocks aren't yet full closures in squeak, YET.

Scriptaculous on Seaside
by Rich Warren 12 Apr '06

12 Apr '06

Hi, I'm trying to use scriptaculous in a seaside app. I've seen references to SeasideAsync, but (as far as I can tell) this appears to only be available for VisualWorks. Can I use scriptaculous on squeak, or do I need to move over to VisualWorks? Thanks, -Rich-

Links list
by Jaroslav Cmunt 12 Apr '06

12 Apr '06

Hi all, I am learning seaside and I am stuck with this code: html table id: 'conceptslist'; with: [ html tableRow class: 'header'; with: [ html tableData with: [ html text: 'Title' ]]. self blogModel concepts do: [ :ea | html tableRow with: [ html tableData with: [ html anchor onClick: (html ajax id: ('concept',ea id asString); callback: [ :r | self editConcept: ea on: r ]); with: ea title. html div id: ('concept',ea id asString) ]]]] No matter what I try, when I click any of the rendered links, editConcept:on: is called with last member of concepts collection. When I was using normal callback (not scriptaculous stuff), everything worked. Thanks, Jaroslav Cmunt
