Fwd: Undirect index update

[Hilaire Fernandes]

Hello Chris,

the point is: I am changing the lexical term object (the object used as
an index) independently (without knowing about) of the objectS (from the
Magma collection) this term is an attribute of (and used as an index).
These lexical terms design a classification, existing independently

Do you mean I just need to send #noteOldKeys: with the lexical term as
an argument? I thought this message should be used with the object from
the Magma collection using the lexical terms as an index.
