small seaside image
by Avi Bryant 25 May '07

25 May '07

A while ago I mentioned on this list a stripped 3.7-based Seaside image that was around 7.5MB. A couple of people have emailed me offlist asking for it, and I've finally gotten around to actually putting one up somewhere. You can grab it from: http://smallthought.com/avi/Seaside2.6.zip This includes Scriptaculous and is up to, I think, around 7.8MB now. Let me know if there are any problems getting or using it. Avi

Wrong URLs with Internet Explorer (again)
by Germán Arduino 13 Jun '06

13 Jun '06

Hi: This is a problem that I've found time ago. Then was not very important because I can manage to use only Firefox, but now I must to expose to Internet a customer application and works ok with Firefox, but when I try to access it using IE, all the urls look bad, as by example: http:///seaside/counter. "Something" is removing the "localhost:port" or "IP:port" from the url, but I can't figure out what thing is generating this behavior. Inside my applications also the "IP:port" look stripped from all the urls. I've tried playing with Resource Base URL and Server Hostname from seaside configuration, but can't solve the problem. I must say also that I'm using ShoreComponents. Any help will be appreciated. Cheers. gsa.

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

OnniBase BTree question
by Dmitry Dorofeev 26 May '06

26 May '06

Hi all, I am using BTree to store session qookies with OmniBase. The code is like this: t := self transaction. "returns current OmniBase transaction" tree := t root at: 'sessions'. b := BMShopBasket new. t makePersistent: b. t lock: tree. tree at: v put: b. t markDirty: tree. t checkpoint. t unlock: tree. I feel it is not very efficient and may be even incorrect way to use BTree. Should I use OmniBase standard BTree implementations ? How can I avoid locking the entire tree ? Thanks, -Dmitry.

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

RE: [Seaside] [ANN] PlotKit 0.8 for Seaside
by Mart-Mari Breedt 04 May '06

04 May '06

Hallo, I really like the new charts, but am struggling a bit to figure out how the labels for the PlotKit pie charts work. Seeing that there is not an xTicks: accessor for the pie chart layout, one would assume that the labels can be set in the dataset. But using a dataset like the one below cause's nothing to be displayed, while passing numeric labels seems to work fine. dataset := PKDataset new name: 'data1'; addX: 'A' y: 1; addX: 'B' y: 2; addX: 'C' y: 3; addX: 'D' y: 4; yourself Kind regards, Mart-Mari -----Original Message----- From: Philippe Marschall [mailto:philippe.marschall@gmail.com] Sent: 10 April 2006 10:42 nm To: The Squeak Enterprise Aubergines Server - general discussion. Subject: [Seaside] [ANN] PlotKit 0.8 for Seaside Hi Alastair Tse took the time and rewrote CanvasGraph.js from scratch and called it PlotKit (http://www.liquidx.net/plotkit/). Now Seaise bindings are available at: http://squeaksource.com/seachart/ So whats new: - a new renderer that looks like Office 2007 - an experimental SVG backend - IE emulation, yes it works in IE! There is also a demo application available at: http://seachart.seasidehosting.st/ that also displays some other seachart components. It uses a free template by Andreas Viklund (http://andreasviklund.com/) Cheers Philippe _______________________________________________ Seaside mailing list Seaside(a)lists.squeakfoundation.org http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside

How does a newbie get past the feeling of trying to understand an elephant whilst looking through a keyhole?
by Stephen Davies 29 Apr '06

29 Apr '06

Hi, I'm trying to get familiar with Squeak. I used Smalltalk/V way back, have and read and understand the Smalltalk 80 book, so it's not completely new to me.... But Squeak is so much bigger. I'm really struggling to get an overall sense of the beast - I can't see the wood for the trees and for me, at least, the environment seems to contribute to that because of the method-by-method interface to the code seems to make it harder to get the big picture. Methods are presented in alphabetical order, without much clue as to how they relate. Similarly for classes. Are there any pointers/suggestions? I feel like I'm missing some tool I don't know about. It's great that you can see everything, but understanding for me would be aided with some sort of "gradual revelation"; a way to replace all the details of a class or bunch of classes with conceptual documentation - showing in a screen or two the overall story of that class's purpose and place in the system. And a way to dip under that to the implementation as needed. Any comments or suggestions for me? Thanks, Steve Davies
