Unexecuted code
by Zulq Alam 19 Mar '06

19 Mar '06

Perhaps it's my lack of experience with Smalltalk but I'm struggling to understand what happens to code which is not executed after an answer. go parameter isNil: [self inform: 'You must specify a parameter.'. self answer]. someObject someActionWith: parameter. self answer. Let's assume that "parameter" is set by some form input which in this case is nil. I would expect the last two statements to execute when "self answer" returns which, as I understand, never will. So, what happens to the last two statements? They must have been on the stack (or whatever Squeak/Smalltalk uses!) and I would assume that "self answer" pushes on to the stack. So doesn't the stack grow indefinitely? Thanks, Zulq.

Seaside & Scriptaculous on PocketPC
by Nicolás Cañibano 18 Mar '06

18 Mar '06

Hi list, I would like to know what are the limitations on using Seaside & Scriptaculous on a PocketPC browser (i.e. Pocket IE). We are planning to use the seaside framework in our research project, involving context-aware applications on mobile devices and distributed systems.

RE: [Seaside] Seaside page design question
by Bany, Michel 18 Mar '06

18 Mar '06

Hi Bruno, Something that may interest you. Annick Fron has created an XSLT Smalltalk code generator that translates XHTML into a Seaside #renderContentOn: method. This would most probably work with Dreamweaver output. Enjoy, Michel. > -----Original Message----- > From: seaside-bounces(a)lists.squeakfoundation.org > [mailto:seaside-bounces@lists.squeakfoundation.org] On Behalf > Of Bruno BB (st) > Sent: Thursday, January 26, 2006 2:17 PM > To: seaside(a)lists.squeakfoundation.org > Subject: [Seaside] Seaside page design question > > Hi all, > > I'm doing my first steps in Seaside. > > Which is the best way to design a complex (in terms of design not > functionality) html page in Seaside ? > > I know i have to subclass WAConponent and rewrite #renderContentOn: > > But it is possible to design a web page with Dreamweaver (or > another design tool) and use it inside Seaside framework ? > Tell to a web disigner to create the skin of the web page and > then use that web page in Seaside. > > Or i have to create small WAComponent with some simple design > and then use them to create a more complex design. > > regards bruno > > _______________________________________________ > Seaside mailing list > Seaside(a)lists.squeakfoundation.org > http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside >

XHTML 1.0 Transitional validation error?
by Rick Flower 18 Mar '06

18 Mar '06

I tried to validate a page I've generated which has a form on it and get the following error from the W3 XHTML validator: 1. Error /Line 2 column 1422/: required attribute "action" not specified. |...ginLeftBox"><br /><form method="post"*>*<input name="5" type="hidden" class="hi| The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element ||. I've tried using a defaultaction for the form and am currently specifying a "with" block.. Is there some other form item I need to use to generate the required action that the validator needs to get a successful validate? By the way, the code generated by the "AllCanvasTests" exhibit the same issue.. Any ideas? I'd love to see 100% compliant XHTML output if at all possible.. -- Rick

Logging out a session (and doing any necessary cleanup)..
by Rick Flower 17 Mar '06

17 Mar '06

Hi all.. Just curious what message I need to send or whatever other steps are needed in order to logout a session that is subclassed from WASession? In this case, I'm not referring to timed out sessions, but rather implicit logouts.. This would allow me to cleanup any crud that was session specific (database connections, etc), etc. On a side note, if I've got a database connection open (in my session object) and the session times out over a period of time, is there a way to get some sort of callback to allow my application to do its necessary cleanup or is there some sort of magic behind the scenes that takes care of it for me automatically (like when the session is destroyed after the timeout is detected)? Thanks! -- Rick

A comprehensive introduction
by Danny Collins 17 Mar '06

17 Mar '06

OK - so I really want to get into Seaside and Smalltalk. but It's been really hard for me to get my head wrapped around the environment, the language and the framework. I was wondering if there was a nice comprehensive (i hate to use this word) introduction, or tutorial that helps to tie it all together? Just wondering, I'm going to continue to muddle my way through it all - I must admit that it is a lot of fun :) Danny Collins

Dynamically updating a WEB page
by Roland Hochmuth 16 Mar '06

16 Mar '06

Hi, Does Seaside have any provisions for dynamically updating a WEB page without the user initiating a callback action? For example, if the WEB page is just displaying a clock that was suppose to automatically update every minute how can it be updated without a user action? What I've done so far is create a callback action attached to the image of the clock. If the user clicks on the image the callback just invokes #answer which returns to the ClockController, which is a WATask. ClockController then just creates a new ClockDisplay, which is a WAComponent, and then invokes #call on it. What I would like to do is have the ClockController periodically invoke a method "update" in ClockDisplay which would force a new WEB page being displayed for the user. Is this where I need to write javascript? Regards --Roland

If I try to load Scriptaculous-lr.37.mcz I get a warning that it depends on WAIframeTag. How do I resolve this? Version 34 does not give this warning. Rick
