The aim of BEFileLibrary is to collate ALL of your javascript and css within the control of one class for your project/site. This will enable a variety of optimisations to be performed by this class. 1. all js/css can be optimized and served as single minimised (TBD) files. 2. The optimised files can be exported to disk for an external server to serve. Seaside file libraries are included like so: include02NiftyCornersCube ^ NiftyCornersCube default '

Correct usage of Comet
by John Toohey 14 Apr '09

14 Apr '09

Hi, I've download the latest Comet build and in less than an hour, had it working with my Seaside 2.9 app. Excellent, as usual, but I have some questions about the correct usage. - How does the disconnect method work, and how and when should I call it. If I am using Comet from numerous components, can it cause problems with the browser, if I don't call disconect. - What is the correct usage of the reconnect method? Thanks. -- -JT

Log Out Without Expiring
by Sigrid E. Mortensen 13 Apr '09

13 Apr '09

I am using Seaside 2.8. I would like to do something different when a page expires than when the user logs out. In the first case, I'd like to put up a page that tells the user the page has expired, and in the latter case, I'd like to just redirect to the log-in page. In the latter case, the session should also be expired, to make it necessary to log in, but it should not tell the user that the session has expired. What is the easiest way to do this? What I have tried is to create my own subclass of WAApplication and override the #handleExpiredRequest: method, wherein I replace the line self redirectResponseFor: url with self redirectHandler redirectPageExpiredTo: url. This puts up the notification when the page expires. However, since I am using self session expire on a log-out, I get the same notification when the user logs out. If I leave in the original code, an expired page and the log-out both go back to my log-in page with no notification. Seems I can do one or the other, but not both. I have considered making my own Session class, but can't figure out how to access it, since self session returns nil in an inspector. Thanks for any help, -- Sigrid.

Re: [Seaside] CSS issue with components on a menu
by Sebastian Van Lacke 13 Apr '09

Thanks Lucas and thanks Julian for the clarification. I was returning the current component as child, but it was another silly error on the code I was not watching. I did not even consider backtracking, I will ask again if anything gives trouble.

Does Seaside allow me to have Apache serve the various Javascript & CSS files?
by Rick Flower 13 Apr '09

13 Apr '09

I was just wondering since Seaside currently uses many of these that are embedded within the image -- if I wanted to have Seaside serve those files up, is there anything that needs to be done on the Seaside end or is it just an issue of having Apache intercept things first and the Seaside stuff just hangs around but doesn't get used? Just thought I'd ask -- I'm not planning on doing this right now but I've been wondering for a while. Thanks! -- Rick

Do you have experience loading UnixProcess into > a running production server under medium/high load? I have a couple > thousand users relying on that image... Michal, No, I do not. I am not actually running any Seaside server. Definitely you should test carefully. I would suggest that you plan for these possible failure modes: - Out of disk space. Probably your backup process should check in advance to verify that sufficient space is available(*), but you may also want to test the effect of trying to do the save with no space available, just to understand the effect of this kind of failure. - Backup process fails to complete, and the image never exits. If for any reason the backup procedure fails to run to completion, such that the background Squeak process does not exit, you would see an accumulation of background Squeak processes that will eventually consume too many system resources(**). - Memory usage. The background Squeak process consumes a very small amount of memory due (processes share address space after a Unix fork, until memory is actually modified). However this may not be the case if your server image is very active and doing garbage collection. Test this and watch for system memory usage issues when you put this into your production system. (*) Here is one way to check free disk space, assuming you have OSProcess and CommandShell loaded. This example is on a Linux system, and I'm checking free block count on the file system that Squeak is using: freeBlocks := (ProxyPipeline command: 'df . | tail -1 | cut -c41-50 ') upToEndOfFile withBlanksTrimmed asInteger (**) The number of running background processes started by OSProcess is: (OSProcess thisOSProcess allMyChildren select: [:p | p isRunning]) size Dave

CSS issue with components on a menu
by Sebastian Van Lacke 09 Apr '09

09 Apr '09

Hi people, I have a menu component that renders the selected component. I need to include a stylesheet depending on which component is selected. Seaside includes all the stylesheets of all the components instead of the selected one's (I have redefine the #updateRoot method in each component to include the correspondent stylesheet ) and some css properties overlap. There is any way to avoid that, without changing the html code or the stylesheets? Thanks!! Sebastian

A little HowTo
by Torsten Bergmann 09 Apr '09

09 Apr '09

Yes, but #canBeRoot should return "true" instead of "True". Otherwise it will return the Boolean subclass "True" instead of its sole instance "true" and the code will not work. Thanks Torsten -- Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger01
