Thomasso, do you know this documentation?

Hi, thanks for your answer.
Indeed in this way it works, because the relation between One and Two is
explicit. However, in this case I am not able anymore to link objects of
the class Three, therefore loosing the dynamic capabilities of both
MongoDB and Smalltalk.
I'll try to investigate a bit more, to understand if it is indeed a bug
or what I am trying to do is simply not reasonable :-)

Hi Tommaso,
that might be a bug… which version are you using?
if latest, can you fill a bug here:
https://github.com/estebanlm/voyage/issues (so I do not forget it)?
thanks,
Esteban

Hi,
thanks for your answer, I also tried with One>>mongoContainer,
but sadly that does not solve the issue.
I think it works in your case because you have the One object
cached from the previous query, but if you inspect the "link"
field, it should be nil.
If you reset the repository connection, it should give the
exception again.
I'll keep trying :-)

Hi Tommaso,
you did not define a One>>mongoContainer. I defined it and then
it seems to work.

Hi,
I am having troubles with Voyage and Mongo.
I have some Classes that I save in Mongo, say "One", "Two",
and "Three".
All three classes and are voyage roots, so the objects from
each class
are stored in different collections.
One objects has a reference to Two or Three objects.
The problem arises when I use a Magritte description and
define a Mongo
container to optimize the storage: since each class is
stored in its own
collection, there is no point in storing the #instanceOf
attribute as well.
Two>>mongoContainer
<mongoContainer>
^ VOMongoContainer new
kind: Two;
yourself
If I add this method, when I try to load an object One, I
get the
exception: "KeyNotFound: key #nil not found in
SystemDictionary".
It looks like Voyage is not able to understand the type of
the objects
stored in the collection Two, when loaded from a reference.
Am I missing something? Do I need to specify something more
to make it work?
I reproduced the scenario in an image that can be downloaded
here:
https://dl.dropboxusercontent.com/u/11506662/VoyageMongo-Link-Test.zip
Do you have any idea? Should I report this on the issue
tracker?
Thanks!
Tommaso
