Nested lists support
by Giger, Bengt 26 May '04

26 May '04

I started a supporting class for Seaside which handles nested lists. Nested lists are commonly i.e. used as a structure for navigation elements, read http://www.alistapart.com/articles/taminglists/ http://css.maxdesign.com.au/index.htm http://www.aplus.co.yu/ADxMenu/ for examples. EWANestedList and EWANestedListNode can represent nested structures of arbitrary level, like menus, file system folders, breadcrumbs etc. They are not based on Seaside classes but use the HTMLRenderers of Seaside to generate nested <ul> blocks when asked to render themselves. As I am new to Smalltalk, there are certainly many possible improvements. I placed a Monticello package here http://www.id.ethz.ch/people/allid_list/bgiger/mc/ hope it can be read, it is (gess) my first package. A supplied example WAComponent which canBeRoot, and comes with some example CSS as a design starting point is running here: http://seaside.ethz.ch/seaside/menulists IE will not render the menus correctly since the examples are pure CSS. I added other classes which build a WADecoration with a menu that works in IE too. In fact this was first and the lists evolved from it. I didn't got the time to refactor EWAMenuBar to use EWANestedList, and to keep IE happy there are some special quirks needed. And I want to avoid ressources outside Seaside, no external files needed for the menus. So perhaps EWAMenuBar and EWANestedLists will live separated for a time. Btw: how do I switch off the configuration footer and stop people editing my squeak image? Bengt Giger

session cleanup
by Marco Paga 25 May '04

25 May '04

Hi. I was just crawling around the list to find a way to release session specific ressources like a database connection. I didn't found a solution for 2.3.2. so here's my little hack to be placed in the application specific session class: isActive | returnValue | returnValue _ super isActive. returnValue ifFalse: [self domainModel closeSession]. ^ returnValue I wanted to write it in one line but the block result is answered. Regards Marco PS: I'm sorry if I was to dumb to see the answer in the list history...

The trick works perfectly with your change. I tried it with the port of Seaside-2.5a3-avi.6.mcz. Some more to learn with the new CSS stuff !! Michel.

[newbie] How do I get the system date and time?
by ld 24 May '04

24 May '04

I'm building a simple logging system in Seaside 2.5a3. When the 'new entry' page is opened, the current date and time should be automatically inserted. How do I get the current date and time of the server Squeak is running on? entryTime _ Time new. returns 12:00 am. I know there's a simple answer, I just don't seem to find it. Thanks for your help. -Larry Kelly

xml & ie
by radoslav hodnicak 23 May '04

23 May '04

I've found out that using the xml declaration (<?xml version="1.0" encoding="UTF-8"?>) when generating pages throws internet exploder into "quirks" mode. After removing it, IE started to behave more sanely with respect to rendering (i.e. it was working in standard mode). Is this even necessary? We are producing xhtml, not xml anyway. rado -- pgp.mit.edu 0x30DEBAE6 12EE FED5 D5B1 77ED 5637 EB77 2A5F 22F9 30DE BAE6

[Mewa] A new instvar in an object isn't rendered in add or edit
by Germ�n S. Arduino 23 May '04

23 May '04

Hi: When I add a new instance variable in an object that is controlled by Mewa, I suppose that the new instvar must be showed automatically by the editor when I wants to add a new object of this type (or edit an existing one), but isn't working. I must do another thing to have my object "updated" to his new instvars in Mewa? (Using Mewa 14 / Seaside 2.3.2) TIA. gsa.

VisualWorks has a #homeReceiver message with two separate implementations for BlockContext and MethodContext objects. When using this message in #findParent, the trickery works just fine. You may want to enhance Seaside and extend Squeak with such methods Michel.

Seaside Widgets & SqueakMap example
by Yanni Chiu 22 May '04

22 May '04

Last week I used SqueakMap to test out a UI layer I've been toying with (that's built over Seaside). If anyone wants to try it out, I've put some code at http://members.rogers.com/yanni/ssui/SQM.st The example uses the SqueakMap objects in the image as a data model for the web pages. I'm thinking of calling it SSW, for Seaside Widgets. The reason it got built is that I found it tedious to code the Seaside pages. Right now, it's probably harder to code the widgets, but I was hoping to be able to use GUI building tools like those for wxWidgets, which can emit XML files. Then the SSW page could be generated from the XML. Comments welcome. (Am I wasting my time? Been down that path before? etc.) If people find it useful, then maybe I could package it up better, for release. Oh, some other things I did with the stuff: - fetch an RSS newsfeed and display it - a SqueakPeople look-alike All of these things are experimental, and may never be cleaned up for release. --yanni

Re: GOODS best practice data storage
by Ken Causey 21 May '04

21 May '04

I see references to interest in code for Doubly-Linked lists. I have an MC Repository at http://kencausey.com/mcrep/ with open read access. Any and all are welcome to any code there just don't expect much. My DoubleLink class is barely more than a stub with the minimal support that I needed at the time for the tests I was doing. Anyone familiar with the concept could recreate it in a few minutes. At any rate you are welcome to it if it helps you, and you can do what you like with it. I've turned my attention elsewhere for the time being and can't say that I will have any opportunity to pursue it further in the near future. Ken

GOODS best practice data storage
by ld 21 May '04

21 May '04

I'm from a RDBMS background, and new to this object stuff. I'm wondering which might be the best way to store information in the GOODS database, for latter retrieval to html tables and forms ,(via Seaside of courst ;). Should I store just the raw data, or is it better to store the object that encapsulates that data? Thanks in advance for you insights, and comments. -Larry
