Loading Latest Monticello.
More recent versions of Monticello provide better feedback as to which
packages are currently loaded.
Select the http://www.squeaksource.com/Monticello repository, click
"open", select the latest package (Monticello-avi.279) from the main
"Monticello" branch, and click "load".
Select the Monticello package on the left hand pane, and the
squeaksource/Monticello repository in the right hand pane. Click 'open'.
In the repository browser, click on the latest version
(Monticello-avi.279.mcz) and click 'Load'.
----
Loading Seaside
Select "world menu > open... SqueakMap"... and a dialog will ask if you
wish to upgrade SqueakMap. Which you do. Notice that SMBase, SMLoader
packages appeaer in the Monticello browser, since the upgrade is
performed by loading Monticello packages.
In SqueakMap, select the ever so convenient "Seaside Installer" which
should load in the whole of seaside with its dependencies in one go. To
do this select the left had pane menu button, "install". (Part way
through the install you will be prompted to enter an admin username
(seaside) and password (admin))
(if SqueakMap doesnt work it is being knobbled by a more recent
package-cache, remove it and try again)
Select the seaside repositoryClick the "open" and the repository browser
will open.
Select Seaside2.6b1 which is the current latest. In the right hand pane
are the releases. Releases may be made by anyone and they may be small
branches off from the main stream. Periodically an effort will be made
to ensure that all changes are merged. Click the history button in order
to browse the history of this package to get some idea of what is going
on. Look at the ancestors of a package to see if one version is being
sequentially built on the next, or whether any branching is occurring.
Seaside is fairly mature and changes infrequent, therefore it is likely
to be safe to grab the latest version.
Loaded Seaside2.6b1-mb.79
Loaded Scriptaculous-lr.137
To start Seaside doit:
WAKom startOn: 8080.
( Or use the "beach flags" SeasideMorph

To test if everything is running, check the following url in your normal
web browser.
http://localhost:8080/seaside/config
you should be prompted for you username and password (as given earlier).

Loading Magma
Back to the Monticello Browser. Deselect the selected package by
clicking on it once. This should re-reveal all of the registered

(It is worth saving this. In the right hand side pane menu button there
is a menu item: "Save Repositories", which writes a simple configuration
script to the working directory.)

Customizing views in Magritte
by Norbert Hartl
Hi,
at the moment I'm playing with magritte to test if it is
suitable for my web application which is done with seaside.
I created a model and I'm able to use it as a component with
seaside. I have a model where ClassA has a 1:m relationship
to ClassB. The exception here is that there is a fixed set
of possible instances for ClassB to choose for the reference
from ClassA.
So what I need on the html rendering side is a kind of a
pull-down and not an extra form for creating new instances of
ClassB.
I read the tutorial.pdf. There are three possibilities mentioned
to customize the views for the model. Unfortunately I didn't
figure out how this is working. The mentioned method defaultContainer
(which should be overridden) doesn't exist in the magritte version
I use. (I is the newest from Monticello)
I even tried to set a new componentClass in the descriptionFoo
class method.But with no effect. I'm not sure what I'm doing
wrong. Magritte seems to ignore every step I take to customize.
What would be the best way to customize on the class or even
better on description instance side?
Why is there an extra componentRenderer? As far as I figured
it out componentRenderer is container dependent. What is the
reason for having a additional method componentRenderer?
What are the best practices for wiring magritte components
together? The only way I found is to use onAnswer:.
thanks in advance,
Norbert

saving image and deployment features
by Martial Boniou
Hi,
I am real interested in seaside/magritte/pier and as a newbie (in squeak but
not in smalltalk) I would like to do a little Pier/seaside website. I
chose to run my squeak process in a linux server with a framebuffer X
server to administrate my image with VNC access (and not by the seaside
inspector available with halos). I did it with a special user (not root)
and my firewall connection configuration permits me to access externally
to my webserver on standard port 80.
But I am a bit unsecure with a deployment of a "classical" pier
configuration. If my machine crash, I lost all my data. So I need to do
backup. I can run a:
SmalltalkImage current snapshot: true andQuit: false.
but if a user does something on my website, it's rejected. So I read
somewhere (maybe thru this mailing-list archive) about a way to do
backup. Actually, I would like to save the image everytime it's
possible. I heard about the use of:
UnixProcess saveImageInBackgroundNicely but I don't know how to use it.
With forkHeadlessSqueakAndDoThenQuit message, it seems to be possible to
save my image in another until I do the permanent and tested weekly
backup. So if I crash or there is a glitch, my image or the periodically
save image can be broken but I can restore the most recent backup.
If someone can explain me how to do (or find how to do) this, I'll be
glad. I don't want to build a wiki/blog like site and lost in a crash
all the readers'comments/posts.
I also noticed some errors in the deployment of squeakfoundation.org. By
clicking on 'Edit' or 'Login', there's error. But instead of permitting
me to go back to the previous page with a short error message (and
advertising the webadmin) like on the other classic php/jsp website, I
go to debug message. It's really bad. I guess that when I click on
'Debug' I open a morph Debugger window on the squeak image. It's not
what I (and probably the squeakfoundation.org webmaster) want. I am sure
there is a way to shortcut the doesNotUnderstand message in seaside/pier
so that in a deployment mode, the user has just a friendly error message
and the webmaster received an email from squeak with the debug message
infos and the context.
So I need your help to try to develop a website with seaside/pier
because I believe in those kind of way to develop websites (I like
servlets too but it's ugly, heavy and I prefer smalltalk as I used
smalltalk or ObjectiveC during the most important part of my life as a
programmer). I thought that I just can develop component and toggle the
deployment preference tag to true, to have a ready-to-use website but
there are missing things. As I said before:
+ how to save in one or two temporary images without stopping the
working pier site? and without going (as I do now) in config page (the
only place when I said 'deployment' to false) to toggle halos and then
to have an inspector which permits me to manually save (I know Lukas did
so too but it's not a good way). There's database way too for
persistence and I will probably look at Magma/REServe and something like
that. I think there are smalltalk that can save multiimage (visualworks
can do this I guess) and it could be a good option that squeak do that
too.
+ how to build a beautiful debug messages to a secure and friendly
deployment? The example of the squeakfoundation.org website is a
horrible one. As with the 'Toggle Halos' button in the
oops-i-didnt-see-i-toogle-deployment-to-false case, it's dangerous and
every visitor can crash or browse in the image without getting the root
seaside admin (that could be nd5 encrypted too).
I hope you will have answers.
Very thanks for reading this a-bit-too-long mail,

Re: RE: [Seaside] [Magritte] Multiple descriptions validation/condition
by Lukas Renggli
> Thanks, glad it's useful. As for beRequired, you got me there, no clue,
> maybe someone else will chime in with the answer.
The latest version of Magritte (Magritte-All-lr.179 or later) has
properties to set the error text for specific error, e.g.
#conflictErrorMessage:, #kindErrorMessage:, #multipleErrorsMessage:,
#requiredErrorMessage: and #rangeErrorMessage:.
The latest version of Pier also makes use of this new feature and now
displays much nicer error messages.
Note that you are required to load Seaside2.7 to use this version of Magritte.
Hope this helps,
Lukas

Re: Reuse of PierSecurity or Spielverderber without Pier in Seaside Application

I'm not really sure how much can be reused besides the general ideas
behind it. I only know Spielverderber but I don't think the situation
is much different for Lukas' package.
The model makes the general assumption that we have commands that
operate on a structure.
There is a user class, a group class, some special group and user
classes that you probably don't want and a command group class.
Besides there is a list class, a list item class and some methods to
find an item in the list.
That was it, the rest is Pier specific.

Magritte Forms
by Ramon Leon
Anyone know if it's possible, to take descriptions from several objects and
display them on the screen all at once?
For example, say I have a Customer object with an addresses collection. But
one data entry screen, I want to flatten it so that the first address in the
collection shows up as fields on the customer form, but the model still
keeps them as separate objects and each field still writes to it's original
model. I looked through Lukas's thesis but didn't see anything.
I was thinking I could override description on the instance side, and add
All the subcomponents descriptors to the main description, but I don't see
how it'd get bound to the subcomponent as it's model.

Magritte Validations
by Ramon Leon
Anyone know of any good resources for working with the validation system of
Magritte. Specifically I'm interested in what it takes to have fields that
depend on the value of each other. Say an end date that must be before a
start date, both of which have just been edited.
I was thinking something like this on the instance side...
description
^self class description collect: [:each |
each accessor selector = #eventEndDate
ifTrue: [each addCondition: [:value | value > self
eventStartDate]]
ifFalse: [each]]
But that doesn't work because I can't rely on eventStartDate having a value
yet, it may not have been set by its description, or it may be invalid for
some other reason. Are the any public sample apps that use Magritte heavily
one could look at?
