The rendering context XHTML document is nil on page refresh
by Damien Cassou 07 Aug '09

07 Aug '09

Hi, sometimes, when I hit the refresh button of my web browser, I get the following stack trace from Seaside. It seems the WARenderingContext has a document which is nil. I'm using pharo1.0beta-10401web09.07.5.image which contains Seaside 2.8a1-pmm.593. Can somebody help me please?

Slime in one click image

Porting Lively Kernel into Seaside
by Michael Ross-1 06 Aug '09

06 Aug '09

Hi, I'm trying to get an idea of how much work would be involved in setting up Lively Kernel (LK) to work in Seaside. (I've done a few webpages in Seaside but have no experience enhancing Seaside code). LK is written in JavaScript, so I imagine that the Scriptaculous package might serve as a starting model for porting LK into Seaside, like storing the LK code as is done in the SULibrary class. It's the Seaside linkage that puzzles me - I don't have a clue what's required here. But I want to keep it simple, at least until the LK demo page is working. So right now, when the demo page starts in the browser, I just want Seaside to serve the LK javascript code to the browser and see what happens. Any tips on how to proceed? what to modify? level of difficulty? Comments? Thanks, -Michael Lively Kernel HomePage at Sun Labs http://research.sun.com/projects/lively/ (best viewed with Safari) -- View this message in context: http://www.nabble.com/Porting-Lively-Kernel-into-Seaside-tp24852667p2485266… Sent from the Squeak - Seaside mailing list archive at Nabble.com.

Seaside one-click 2.8.4 experience on windows
by Stephan Eggermont 06 Aug '09

06 Aug '09

- I downloaded the 2.8.4 one-click yesterday on windows, and noticed the right mouse button doesn't work by default. - I managed to get the OBBrowser to not handle ctrl-s and not ask for author initials. Haven't been able to reproduce, though. - I installed Atom-avi-7 from squeaksource. Its dependency on XMLDomParser is not shown. Shouldn't the one-click have XML support? - I tried to periodically load a feed with Scheduler,but that seems to be incompatible with closure images. Stephan

Generated links (anchor -> callback)
by Mark Ross 04 Aug '09

04 Aug '09

Hi seaside list! I'm roughly new in developing seaside. Trying out some seaside development. I'm using: GemStone/S 64 Bit 2.3.1 Build: gss64_2_3_x_branch-20643 Thu Dec 4 11:33:32 2008 with GemTools 2.3.1 I would like create links on my page - with generated URLS, which have the value of the index from render time. I try by using something like this: initialize super initialize. self value: 0 renderContentOn: canvas canvas text: self value. 1 to: 10 do: [ :index | canvas anchor callback:[ self value: index ]; with: index. html space ]. -> The value is everytime clicking on a link '10' - which I would understand, if i didn't read the tutorial on the seaside.st site: -----snip ----- renderContentOn: html 1 to: 10 do: [ :index | html anchor callback: [ index inspect ]; with: index. html space ] It will generate a series of links, labelled from 1 to 10. Because the action blocks capture the current value of the i variable, each one will have a distinct callback: clicking on the "1" link will evaluate 1 inspect, on the "2" link will evaluate 2 inspect, and so on. The block closure is being used to maintain all of the interesting state for the link. -----snap----- Please, can somebody help me out finding my mistake? Best regards Mark

2.9 alpha 4
by Ramiro Diaz Trepat 03 Aug '09

Hi, I wanted to install Seaside 2.9 to give it a try. I got a Pharo dev image, and I downloaded the Monticello Configurations file from builder.seaside.st This mcm failed during the installation process. Then I tried the .cs and that one did install without problems, but when I access http://localhost:8080/seaside I get a response from Kom, as if it were unrelated to Seaside. Cheers r

[Seaside 2.9 VW] WARenderLoopContinuation>>updateRoot:
by Karsten 03 Aug '09

03 Aug '09

Hi, I've noticed that WARenderLoopContinuation>>updateRoot: only visits the visible presenters. This doesn't take into account #lightbox:, where the caller is still visible, even though the Lightbox decoration is a delegation. The result is that the caller's updateRoot: is not called and the caller's stylesheets are not loaded. Maybe WAVisiblePresenterGuide>>shouldVisitNextPresenterOf: should ask the decoration if its next presenter is visible or not.

launchd headless on Mac OS X
by Aaron Rosenzweig 02 Aug '09

02 Aug '09

Hello Everyone, I want to run either a Squeak or Pharo VM as a "service" in Mac OS X. That means a few things: * headless operation * automatically loads when the OS boots * safely quits when the OS shuts down * preferably controlled by launchd (launchctl) I'm sorry if some of us are seeing "double" as I started posting first on the Pier list. There was some discussion there that has led me to start experimenting with VMMaker to try and solve my problem but while I'm doing that, I thought I'd post here. This really shouldn't be so hard. I see so many screencasts for Seaside done on a Mac and the one-click installers work so well on a Mac. Surely someone has tackled this issue before. The one-click installers work pretty good. They even launch headless if you start them from the command line with the "-headless" option but only from a terminal window. You can't start them headless from launchd because it seems they are Carbon apps which require some minimal communication with the window server during startup. Sounds like a contradicted myself but it's true. If you have a login session, fire up terminal, then run headless that works. If you try to use launchd you get an error like this: -headless: kCGErrorRangeCheck : Window Server communications from outside of session allowed for root and console user only So, I'm about to try the Pier one-click installer and use VMMaker to produce a "unix-only" source tree that I compile that does not rely on Carbon to see what will happen. Any help appreciated :-) Thanks in advance, -- Aaron
