Re: [Metacello] collecting all packages of a configuration

Dale Henrichs — 2012-05-17T21:14:28

Mariano,

Metacello let's Monticello do the initialization, but decides which sets of packages to load at the same time ... #atomic projects load all of the packages at once, then initialize. While #linear projects load and initialize each package individually ... I believe that Seaside is #linear.

Things can get a bit complicated when #atomic and #linear projects are intermixed (via dependencies) 

If you throw a `Transcript show` into the postLoadOver: method (at least that seems like the right one) and run Metacello, you'll have a record of when each package was initialiazed during the load. 

You should be able to tell from loadDirective structure what's going to happen...oh wait there are preload and postload doits besides the standard initialization stuff ... but that too is in the loadDirective structure ... typically the ExplicitLoadDirective is used to get a Configuration loaded "right now" during fetch, so focus on the AtomicLoadDirective and LinearLoadDiretives...

If you want to duplicate what M

Re: [Metacello] collecting all packages of a configuration

Mariano Martinez Peck — 2012-05-17T18:13:41

I should explain what I am doing. I am exporting packages using Fuel. What
I do is to query Metacello to know which packages I need and the order (for
the future load).
Then, during load, after having materialized all packages, I iterate over
the packages (in the order I stored during the export), and I initialize
the classes for each package.

In this example, I am NOT upgrading nothing. I am just trying to import
seaside in a clean image using Fuel.





indeed, it works fine.




Indeed, I also thought that I have a problem with the initialization. I
sent this mail because maybe this particular problem moves some bell ;)





You mean MCMethodDefinition >> postloadOver:  right?



yes, you mean the if:    self source ~= aDefinition source   right?
In my case, I am loading methods that DO NOT have source code. So..


mmmm #atomic  loader type?  where can I see more info about this?



where can I see this?

Thanks

Mariano,

I guess you are trying to upgrade an existing Seaside application? 

Are you having trouble doing this upgrade using Metacello, or is this a problem trying to do the upgrade using the package order derived from the loadDirectives?

If the Metacello load works fine, then I would guess that you're not running your initializers in the right order at the right time. Your little loop over packageNames looks close to what Monticello does when it fires the initializers, but it's not quite the same ... for example Monticello only fires initializers for class initialization methods that are changed/new during the load. 

Also, if I remember correctly Metacello fires the initializers for Seaside packages immediately after the package is loaded and does not wait until the end to fire initializers ...

I'd focus on duplicating the initialization pattern of Metacello (instrumenting the Monticello loader where the initializations are fired would give you that info).

Re: Render into a separate document while sharing context

When I send a 'reset your password' email I think I'm doing what you're 
asking about in your original question. e.g.

MyWAComponentSubclass>>#sendPasswordResetLinkToUser:html
newUrl := html context actionUrl
withParameter:
(html callbacks
store:
(WAValueCallback
on: [self home.
self show: (ResetPassword new user: member) ])).

urlToEmail := html context resourceUrl greaseString , newUrl greaseString.

self sendMailWithUrl: urlToEmail toMember: member.



So when clicked in their email their browser opens up the 'reset 
password' form in a page on my site.  It doesn't use WABuilder and does 
store a callback that does get executed in the current render context. 
It also expires when the current session expires.

Or different asked:

Using

WARenderCanvas builder render: [:h| ...]

enables me to render something into a string. But if the rendered block produces callbacks they aren't registered anywhere and cannot be called aftwards, right?

Hi Dale. Now I was a little bit more sucessful. But still, I have a problem
during the initialization of classes. More precisily in:

WAWalkbackErrorHandler class >> initialize
    WAAdmin applicationExceptionHandlingDefaults at: #exceptionHandler put:
self

I get a WAAttributeNotFound with #exceptionHandler ...  what I do is I
follow the order of packages as Metacello answered me, and then I do
something like:

(packageNames collect: [:each | PackageInfo named: each])
            do: [:aPackage |
                "We should not send #initialize to traits"
                ((aPackage classes select: [:each | each isBehavior])
                     sort: [:a :b | a allSuperclasses size < b
allSuperclasses size ])
                         do: [:aClass |
                            Transcript show: 'Initializing class named: ',
aClass name; cr.
                            aClass initializeOnLoad]
            ].
        ]


I have debugged a little bit and it looks like

I don't think so. You are tunneling virtual callbacks over one real callback. But that one real callback you need to draw in this canvas. My problem is the place where the rendered string should be drawn. Basically I have

So I have anchor1 that is rendered on the canvas. Then I need to render a script on that canvas that creates a marker on a map.

Lawrence,

In VisualWorks you can use message catalogs to do the translation of
UserMessage instances during rendering depending on the locale of the
session,

 with: #Company << #raven

 encoding: #UTF_8

Render into a separate document while sharing context

Norbert Hartl — 2012-05-16T16:16:55

I'm doing a page at the moment that contains a google map. On the html page there is a list with all entries and on the map there are the markers on the geo position. 

To place a marker I need to call some javascript function. That function takes latitude, longitude and a definition of a window that pops up if the marker is pressed. The popup window needs to contain an html anchor. Therefor I need to add the callbacks to the current renderer.

Is there something that assists in doing this. WABuilder would be fine but it creates a new render context. 

thanks,

Norbert

The body I request via

in the latter you need to check if you get a string or a WAFile. And you need to decode manually
