[ANN] Extraction of Pillar from Pier

Dear readers,

I've just extracted Pillar out of Pier (baseline 3.10). Pillar is a
syntax (the good-old Pier syntax), its parser, a document model, and
exporters. Pier now depends on Pillar and provide a CMS (with its
Morph and Seaside views).

Magritte Editor issue?

Hi all,

I’m attempting to teach myself magritte and was looking at the seaside magritte editor example and had a question:

In the editor when I select Single Option (or multiple) I get the error: 'MADescription is abstract.’

>From the stack it looks like it’s created an ExternalEditor which then uses a ToOneRelationDescription, and when it tries to get a reference it’s attempting to create a new MADescription… causing the error.

Is this what it’s supposed to do? I seem to remember playing with the editor (a long time ago) and it all working… but that’s probably my mind playing tricks.

I built a fresh pharo 2 with only magritte and seaside and found the same issue. I tried a fresh 1.4 but had errors loading magritte and was too lazy to work them out :)

Should the editor work with all the description types in the popup?

Cheers,

Jupiter

could you please give us all the steps to reproduce your problem?
Starting with "Download this stuff there" is important.

Re: Magritte Editor issue?

Hi Damien,

Thanks for the reply.

Absolutely :)

I started with Pharo 2 image 20619 and vm pre-6 for mac os x.and did the pharo system update.

from... MCHttpRepository
location: 'http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main'
user: ‘’
…downloaded… ConfigurationOfSeaside3-PaulDeBruicker.68
…and loaded with… (ConfigurationOfSeaside3 project version: #stable) load

and from... MCHttpRepository
location: 'http://www.smalltalkhub.com/mc/Magritte/Magritte3/main'
user: ''
password: ‘'
…downloaded… ConfigurationOfMagritte3-TudorGirba.56
…and loaded with… (ConfigurationOfMagritte3 project version: #stable) load

…then installed… Magritte-Seaside-NickAger.354

That’t it.

Did I load the wrong stuff?

Thanks again.

Cheers,

Jupiter

Fwd: Magritte Editor issue?

I forgot to then mention that to reproduce the error, try creating a “single-option” (or multi- or a couple of the other descriptions). When you click add, the exception occurs.

Thanks again.

Cheers,

Jupiter

I can reproduce the problem. Detailed steps:

ZnZincServerAdaptor startOn: 8080.

Open http://localhost:8080/magritte/editor, select "Single-Option",

Re: Magritte Editor issue?

Hi all,

I probably should have spoken up sooner about this. sorry.

The problem is related to the fact that, in Magritte3, you have to instantiate a class before you can access its description.

MARelationDescription>>reference attempts to get the description of the class returned by MARelationDescription>>commonClass. But the commonClass is MADescription and instantiating it fails because it is "abstract". You could change MADescription>>isAbstract to return true and it should work but that could break something somewhere else. (I do not have an image handy with Magritte3 installed or I would try it myself). Otherwise, have a look at MAReferenceDescription class>>descriptionReference and you will notice that it builds its classes from MADescription allConcreteClasses. This is what causes the commonClass method to return MADescription. Perhaps changing the base class to MAElementDescription might work?

Hope this helps.

John

Re: Magritte Editor issue?

The attached filein fixes the issue.

With Magritte-XmlBinding installed, you get other errors related to xmlTarget having an identity crisis as it either DNU xmlAttributeName or DNU xmlElementName. The description of an MAElementDescription attempts to send both messages to the model. This occurs without the attached fix so its not related. My image is Pharo1.4 from a Pier3 One-Click I believe.

I am mentioning this on this thread because it appears to be only related to the edtior.

Best regards,

John
