Re: [Magritte] Relation description with instances of a class

Yes, those two already duplicate some code, traits would be of a big help here ;-) Anyway, I would subclass the ToOneRelation and try to copy the things you need from the SingleOptionDescription (probably only #options) over into your new class. The same for the views. No, that should work with any block of code. However MADynamicObject does not work together with the Smalltalk Debugger, as the debugger tries to evaluate the block again when displaying the object in its inspector causing yet another error and debugger ... So one thing you have to make sure beforehand is that the code in MADynamicObject works as expected by copying the contents of the block to a workspace and testing it there. I tend to discourage the use of MADynamicObject because it usually causes more troubles than it solves. It is much a better approach to create your descriptions dynamically on the instance side, if you need to build them depending on the state of your model.
