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

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!

by Sebastian Sastre 11 Jun '07

11 Jun '07

Hi there, I wonder if anybody has done some CSS programatic manipulation. For cases in wich the look of a component should depend on some instance state it could be interesting. Has anybody do this? found interesting? found limitations? cheers, Sebastian Sastre

JOB: GemStone/S QA Engineer
by James Foster 31 May '07

31 May '07

JOB SUMMARY This engineer will be part of the GemStone/S engineering team in Beaverton, Oregon, and will focus on product testing. Since most of the tests are automated, the work primarily involves writing and debugging Smalltalk code. PRODUCT AND TEAM GemStone/S was introduced at the first OOPSLA in 1986. Since then it has earned a reputation in the Smalltalk programming community as being the premier object database and application server. GemStone/S allows thousands of Smalltalk virtual machines on hundreds of hosts (with various operating systems) to share a single image (or database) with billions of objects taking up terabytes of space. The database provides full ACID capabilities (atomicity, consistency, isolation, and durability), has extensive indexing and large collection support, and includes a number of sophisticated garbage collection algorithms. The Smalltalk virtual machine has a JIT compiler on several platforms and supports a shared object cache effectively limited only by the amount of memory available in the machine. GemStone/S has an add-on product, Gem Builder for Smalltalk (GBS), which supports transparent object replication for VA Smalltalk and VisualWorks. Other add-on products provide an interface to Java and Oracle. GemStone recently announced support for Seaside (a Smalltalk web application framework) and availability of a 4 GB edition that is free--even for commercial use. The GemStone/S team consists of about 10-12 people. This group has a very low turnover and includes a number of senior-level engineers who have decades of experience in areas such as VM architecture, database internals, application development, and consulting. Team members regularly present at industry conferences such as Smalltalk Solutions and OOPSLA. ESSENTIAL JOB FUNCTIONS * Design and develop complex functional, performance, and scalability tests and test frameworks. * Run tests, analyze results, and work with other engineers to identify and resolve issues. * Be self-directed, assertive, and able to concurrently work on multiple tasks. * Have a commitment to software quality and performance. * Adhere to company coding guidelines. KNOWLEDGE, SKILLS, ABILITIES AND EDUCATION REQUIREMENTS * BS Computer Science or equivalent, including understanding of: o Database record/object locking, transactions, backup & restore; o Multi-user concurrency; o Multi-threaded applications; o Network communications; and o Software engineering principles and methodologies. * Moderate experience (e.g., 3+ years) in: o Developing large client/server database applications; o Testing, including performance and scalability testing; o Developing test frameworks and tools; and o Smalltalk and object-oriented programming. * Experience (e.g., 1+ years) in: o Unix/Linux shell programming; o Source code management tools; o C/C++ programming; and o Perl programming. CONTACT Send email to resume(a)gemstone.com and include 'Smalltalk QA' in the subject.

Almost perfect Philippe, because I don't want to change all my buttons whether some of them or just one and the another have to stay in the same colour, I hope you can help me, is it possible to use conditions inside CSS??
