Voyage and Instance Mode

Hello all.

I'am learning to use Voyage by trying the examples in the Voyage doc (in the Enterprise Pharo book).

I read "By default, Voyage works in instance mode".

If I run the example in instance mode, I get an error via the debugger.

|repo anAssociation|

repo := VOMemoryRepository new.

anAssociation := #answer -> 42.

anAssociation save: repo.

==> "Instance of Association did not understand #save:"

What am I doing wrong?

Re: Voyage and Instance Mode

Thanks Esteban.

I was fooled by the doc : "In instance mode, the first argument is always the repository on which to performed the operation"...

Well, not really, but the object to store.

Re: Voyage and Instance Mode

Can you do a pull request to update the book?
Or do we let rot the documentation?

Is the same sentence present in the Voyage booklet?
