Hi Mariano,
Hi Lukas. I was serializing Pier kernels with Fuel and
I started to face
problems with Magritte proxies. Since I have no idea how/why they are use, I
need to ask a couple of question. Imagine I want to serialize a graph (like
a Pier kernel) that contains instances of MADynamicObject, like
MAMultipleOptionDescription new
default: [ self defaultViewClasses ] magritteDynamicObject;
options: [ self defaultViewClasses ] magritteDynamicObject;
....
The reason to have them is to allow Magritte to cache the description
instances, while certain properties can still adapt to the model.
So the questions are:
- When I MATERIALIZE the graph, would you like to
a) still have the proxies exactly as it was during serialization ?
b) or would you expect that objects refer directly to the target of the
proxy (proxies do not even exist) ?
It doesn't really matter because the descriptions that end up part of
the model are just there to identify a certain described value. The
description itself is not used other than to compare it with other
descriptions. So the best is probably if you just nil the proxies on
serialization.
