Version 2.5b6 for VW is ready
by Bany, Michel 06 Nov '05

06 Nov '05

I just published Seaside 2.5b6 for VW on the public repository. It is based upon Seaside2.5b6-avi.8.mcz 15-Jan-2005 16:15 i.e. the very latest version of 2.5b6. This port includes all the fixes that were discussed here: - file upload - lost halo icons and missing styles Note: I also fixed Seaside 2.5b5 on the public repository. For the fun, I added the Seaside logo on some of the pages. Bundle to load : either SeasideForWebToolkit or SeasideForSwazoo. Enjoy, Michel.

Nested form tags
by Bany, Michel 04 Nov '05

04 Nov '05

I came accross some weird situation when using a component that is a composition of other components. A subcomponent may in turn be a composition of some more components. To make things even more complex, some deeply nested subcomponents may call some other component. Some of the subcomponents may contain some input html tag and as such will require to be contained in a form html tag. In such a complex construct it may be difficult to decide exactly what component should have the responsibility to generate the form tag. Also, it happened frequently to me that form tags become nested especially when a subcomponent calls another component that happens to be a dialog. Therefore I am making the following suggestion : Seaside should prevent form tags from being nested. It should discard any form tag that occurs within a previously opened form tag. With this in place, I can design a component that needs a form with a form construct knowing that if my component happens to be used inside a form, then my form construct will be discarded. Otherwise my form construct will be preserved. If my component calls a dialog component, the form generated by the dialog component will be discarded if my component happens to be used from inside a form. Michel.

Ok, 1500 concurrent sessions is a very big number; that's pretty consistent with your image sizes, so I agree it probably doesn't have anything to do with GLORP etc. But even with a 100 minute time out that sounds awfully high; do you really think you get, say, 10000 visitors per day? Or is something else going on? Either the peaks are very, very heavy, or there's something wrong with the expiry. One instrumentation that would help here would be to simply log every time a session is created. That should barely affect performance and would be a good indication of what's going on. > I might have gotten hit with a DOS attack or something on Thursday and > Friday, I don't know. The traffic numbers certainly would seem to support > that possibility. Yes. I wonder what strategies we can use to detect and cope with that. One I can think of is to link the expiry time to how much the application has been used: if all you do is request the homepage, your session will expire very quickly, but if you look around a little more you're given more time. That seem reasonable? Avi

CSS Editor Recomendations?
by Guenther Schmidt 02 May '05

02 May '05

Hi, I wonder if anyone could suggest a good CSS editor to me. Most tools for "designing" Webpages seem to want to alter the HTML code by writing inline. Anyone know of an (WYSIWYG) editor that leaves the HTML alone and create external stylesheets? Günther

urlForDocument
by Cédric Mesnage 29 Apr '05

29 Apr '05

Hi, I'm working on a VRML/X3D Component for seaside, I already have done a library to create that kind of documents and a WA3d component. The problem I have is that sometimes (often), the document is said : 'That page has expired.' ... Here is what I am doing in the rendering method of the WA3d component: renderContentOn: html url := html context urlForDocument: x3dDocument asVrml mimeType: 'model/vrml' fileName: 'vrml.wrl'. html attributeAt: 'src' put: url. html attributeAt: 'width' put: '600'. html attributeAt: 'height' put: '400'. html tag: #embed. The fact is that (x3dDocument asVrml) works all the time so I just can't figure out why sometimes the document is unreachable. If someone experienced the same problem... Thank you for any suggestion. -- Cédric Mesnage Master 2 Student in CAEN cedric.mesnage(a)gmail.com

Thank you, I just figured out you can also do it without a cssId like this: html attributes at: 'valign' put: 'top'. _____ From: Bany, Michel [mailto:mbany@cincom.com] Sent: 28 April 2005 03:52 PM To: The Squeak Enterprise Aubergines Server - general discussion.

U use this implementation: loadStaticDocuments Smalltalk at: #StaticDocumentsRepository put: Dictionary new. (FileDirectory on: (FileDirectory default fullPathFor: 'resources')) fileNames do: [ :fileName | self loadStaticDocument: fileName ]. loadStaticDocument: fileName | path | path := (FileDirectory default fullPathFor: 'resources'), FileDirectory slash, fileName.
