RE: Magritte Validation Error

No, it is the call to isKindOf from the super class that is failing, the call to includes works fine. My project class does implement #= and hash, and uses a UUID string for identity. self kind is resolving to Class class, since isKindOf is being sent to anObject, that should resolve the proxy, so perhaps something is wrong with: descriptionProject ^(MASingleOptionDescription selector: #project label: 'Project' priority: 10) reference: MAClassDescription new; options: (MADynamicObject on: [ TMProject repository asArray]); beRequired; beSorted ; yourself MAClassDescription seems wrong, looking now, I see why isKindOf is failing, I'm not filling the dropdown with classes, but I don't see what's appropriate, without it I get MessageNotUnderstood: TMProject>>do:. So how do I use other domain objects in a SingleOptionDescription rather than just a simple list of symbols or strings? ________________________________ From: owner-smallwiki(a)iam.unibe.ch on behalf of Lukas Renggli Sent: Mon 11/28/2005 5:41 AM To: smallwiki(a)iam.unibe.ch Subject: Re: Magritte Validation Error The method #validateKind: for MASingleOptionDescription look like (I merged in the super-call): MASingleDescription>>validateKind: anObject (anObject isKindOf: self kind) ifFalse: [ MAKindError on: self ]. (self isExtensible or: [ self options includes: anObject ]) ifFalse: [ MAKindError on: self ]. anObject is used as a receiver for #isKindOf: and #= within #includes:. I think the #isKindOf: should resolve any proxies, but there is probably a problem with the #includes:. I think the point is that your project-class doesn't implement #= and therefor defaults to #==, so you the #includes: identity-compares every project with the proxy ... what fails of course.
