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.

Unused instance variable?
by Samuel Tardieu 12 Dec '04

12 Dec '04

It looks like the "session" variable of "WAMain" is unused. Sam -- Samuel Tardieu -- sam(a)rfc1149.net -- http://www.rfc1149.net/sam

hi! Here, at the University of bern, we are currently doing a lecture on Seaside. Does Seaside have a logo ? It would be nice if it would...

Home link
by Yar Hwee Boon 05 Nov '04

05 Nov '04

Have read through the various threads such as "How to do the ubiquitous home button?", do we still do it by implementing WAComponent#clearDelegate? Also, are there any consequences to sending #call: to a component multiple times? ie. I have a navigation bar with several links where each of them does a #call: to show the respective component. I'm trying to use the home link to, well, go back to home. Comments? -- Regards HweeBoon MotionObj

Image shrinking
by Chris Reuter 03 Nov '04

03 Nov '04

In the course of my current project, I did some work getting the image size down to something reasonable. I managed to get it down to 2.6 Mb while still containing Seaside, Commanche, YAXO and SIXX plus the MVC-based IDE. The Big Ball o' Scripts (plus some documentation) is here: http://www.sentex.ca/~cgreuter/downloads/MiniWeb-1.0.zip It needs to be filed in to a pristine Squeak 3.4-5170 image to work. The changesets for Seaside et. al. are in the zipball. I can't vouch for its reliability except to say that I've used it (the resulting image, that is) to do development on my old laptop and haven't had any problems. --Chris -- Chris Reuter http://www.blit.ca "I pay way too much for cable, so I have to watch what's on the premium channels, even if it's not very good, or else I'm just throwing money away." --Gregory King in alt.religion.kibology

No error message if DNU when downloading scripts from WAScriptLibrary subclasses
by Yar Hwee Boon 02 Nov '04

02 Nov '04

If a DNU (for eg., forgetting to put a ^) is raised while downloading scripts through the WAScriptLibrary (and I guess styles from WAStyleLibrary too) mechanism, the error message is only viewable if you explicitly do a download of that script file. Should there be a debug link? Since there was a discussion of logging the transcript contents as a panel in the webpage, maybe it would be useful to show an error message there? -- Regards HweeBoon MotionObj

RE: [Seaside] How to do validation such as for money (with a curr encyclass) in WAEditDialog subclasses?

I would use the command pattern, i.e. the model of your Seaside component should be a command. You would collect all the command data using the callbacks of your component Then the callback attached to the OK button would send #execute to the command object. Assuming that #execute performs the validation, you would get an exception describing the error(s). On the next rendering, you would alter the display to using the error description(s). Did you have a look to Mewa ? It does validation using another technique where you have a meta-wrapper for every aspects of the domain object. But again the domain object is not updated directly. Hope this helps, Michel.

Lists and ownership
by Jim Menard 01 Nov '04

01 Nov '04

I have a list of things (an address book), and I'm writing a simple Seaside app to display the list and CRUD entries. I have a bunch of basic, related design questions. Any help will be greatly appreciated. There are a lot of questions here; answers like "go read XXX" would be just as helpful as direct answers. I have read the few Seaside tutorials and docs I've been able to find. Who should "own" the list of entries? Should I create the list as a class instance variable of the entry class, or as a global entry in Smalltalk? How should my WAComponents access the list: by holding a copy (won't modifications to the list will be lost?) or by asking for the class instance variable/Smalltalk entry every time they want to access the list? What should I register for backtracking: the list itself? Each of the list entries? I'm looking at WATableReport, but I'm a bit confused about how to hand it my list of entries. Do I need to create WAReportColumn objects for each instance variable of each entry? Are these even the right questions? :-) Thank you for your help.

WAMiniCalendar bug? #date: should set #month
by Yar Hwee Boon 31 Oct '04

31 Oct '04

I think WAMiniCalendar>>date: should set #month in order for WAMiniCalendar to work properly. WAMiniCalendar>>date: aDate date contents: aDate. month contents: aDate month "Added" Just curious.. does #month, etc exist mainly as an optimisation? -- Regards HweeBoon MotionObj
