Re: Magritte- MAProxyObject, MADynamic object

It is rarely used, I try to avoid its use as much as possible. MAProxyObject is an abstract class. MADynamicObject is created when sending the message #asDynamicObject to a block. The idea is to have dynamic properties in descriptions (or other objects). For example in Pier the owner of a structure is described on the class side with something like: MASingleOptionDescription new beSorted; label: 'Owner'; selectorAccessor: #owner; reference: PUUser description; options: [ self allUsers ] asDynamicObject; yourself This means every time the options are queried the sender gets a proxy object that (most of the time) resolves to the list of all available users. Again, this is cool magic that works most of the time, but I strongly discourage to use it. In all cases it is possible to avoid its use all-together, for example by overriding #description on the instance side and adding the description manually instead of defining it on the class side. I am just too lazy to do that sometimes ;-) Cheers, Lukas -- Lukas Renggli http://www.lukas-renggli.ch
