section 4.1:
The Adaptive- Model has two instance variables, the first being used to refer to the
descriptions of the instance and the other one to keep a list of the actual values of the
model. Transforming the class of the adaptive model into a Trait [18] allows us turn any
existing class into an adaptive model and to combine the descriptions defined in the class
with the ones provided by the instance.
I cannot find this trait. Does it exist in magritte? I see MAAdaptiveModel, but I am
indeed trying to add adaptivity to a class, and am struggling with it

Well, I think I at least figured out how to implement it. My issue was how to detect
whether a given description is a regular one, or an adaptive one, in the implementation of
#readUsing:. However, I then remembered that PRComponent already needs to do this, and so
I looked at it’s code. It does
(self basicMagritteDescription includes: aDescription)
That still leaves the question though, does this trait version of MAAdaptiveModel exist?

Hi,
I have not read the article, but from what you describe I think Magritte already has an
adaptive model, although it is not very explicit.
All objects can be asked for a magritte description on demand, and based on this
description the components are generated. The components usually use a cache for the
values, where the values are read from and stored into when the user makes changes. So,
the components have a reference the description of the model and to the actual values of
the model.
Regards,
Diego
