A strange Magritte issue

by Brian Brown

Hello, I have a model class called ALServiceContact that is using Magritte, like I am with my other model classes. This class has 6 descriptions (string, memo, 3 single options, and a date). Two of the MASingleDescription descriptions use a list of other model objects as their options. One points to a list of providers and one to a list of customers. The Magritte form builds (asValidatedForm) and displays as I expect, but when I try to save it, Magritte is giving me validation messages for descriptions from a different class. The class I am getting the validation messages from is called ALCustomer, and is only involved with ALServiceContact through: ALServiceContact class>>descriptionClient ^ (MASingleOptionDescription new) selectorAccessor: #client; label: 'Client'; priority: 20; options: ALStorage rootOrg customers; reference: ALCustomer description; comment: 'A Customer'; yourself on the ALCustomer class, I have required fields for four descriptions, and these are the messages I get: Status: Invalid input given Title: Input is required but no input given Organization: Invalid input given Email: Input is required but no input given ...when I try to save an ALServiceContact created with: add |contact| contact := self call: (ALServiceContact new asComponent addValidatedForm; yourself). contact isNil ifFalse: [ self contactManager addContact: contact. self report refresh] Of course, ALServiceContact doesn't even have those descriptions. Very Strange stuff! Any thoughts? Brian

Magritte MATableRenderer

by Brian Brown

I would like to use the default MATableRenderer, but have a div surrounding it so I can apply styles to it easily; I can subclass it to add what I want, but is there a way to have the Magritte machinery use my custom one? I think I understand how to add custom descriptions for classes, but that doesn't impact the MAContainer that renders the descriptions.... And it's likely that I don't understand how this all fits together :-) Help! Brian

Easy way to make many similar descriptions at once?

by wagwilk＠telusplanet.net

I'm trying to create a magritte form for surveys used at our company, where many of the field are identical. Surveys consist of a header, for which I've created magritte descriptions in the standard way, and questions which are answered by a rating (an integer of -1, 0 or 1 or nil) and an optional comment (a string). For this particular survey, there are 18 questions; I'd like some advice on how to best use magritte to describe them. I've heard of 'multiplicites' in the context of OneToMany relations -- so this is probably not what I want -- but is there a count attribute in magritte descriptions? I'd like to avoid copy/pasting 18 field descriptions if possible. Cheers Warren Wilkinson

MAOneToManyComponent>>value not getting set

by Chad Nantais

When trying to add a new item inside an MAToManyRelationDescription container, I get the error found in the attached file. It says that the MAOneToManyComponent>>value is an undefined object. I reproduced this error in the MADescriptionEditor example as well as in my code. I'm using the latest Magritte-all package. Chad

validation of referenced objects

by Norbert Hartl

Hi, I have an image object which references a user. For the user there is a descriptionContainer which adds conditions for the user (checks equality of password). In a component dealing with the image there appears something strange. If I do a validate on that component it complains abaut value cache being unknown. And this is coming from the descriptionContainer of the user object. Is it normal for the referenced objects to be checked as well? Or do I misunderstand something? thanks, Norbert

MASingleOptionDescription or MAOneToManyDescription?

by Brian Brown

Hello folks! I'm finally diving into Magritte and things are going quite well in general. I have one situation I can't quite figure out how to solve.... I have a Person class with in ivar that holds an Organization. I would like to present a drop down list of Organizations when editing the person. I have tried various permutations of MASingleOptionDescription and MAOneToManyDescription, but I am not groking how they should be used :) For example, I have tried an OrderedCollection of Organizations as the argument to MASingleOptionDescription>>options:, among a bunch of other things I tried, but no joy. Anyone have any suggestions for me? thanks! Brian

MAReport status

by Damien Cassou

Hi, what is the status of MAReport? A student uses MAReport to display a list of models. Each row has a #remove: command associated. The problem appears if the user click on a header to sort the table and then click on the #remove link. The table is not refreshed. Callin #refresh reset the MAReport and puts it on the first page :-( Can you help me? -- Damien Cassou

Magritte component customization

by Ramiro Diaz Trepat

Hello again, I want to use a Magritte Seaside component with a different set of actions / buttons than the default ( save / cancel ) Looking through the list, I found that the required thing to do is to program the extensions to MAContainerComponent, and then build the component with a call like this: (self model descriptionRequiredFields asComponentOn: self model) addValidatedForm: #( register cancel ) What I am not sure about, is what is the proper way to do this extensions. Should I subclass MAContainer and override #componentClass to make it return a subclass of MAContainerComponent (of my application) that implements the actions I need (like register in the example above) ? Has anyone got an example of this sort of action overriding in Magritte forms? Thanks r.
