EcoreUtil.copy() for bidirectional references [message #1211604]

EcoreUtil.copy() does not copy bidirectional links where both ends are not part of the copy, for good reasons.

However I have the following situation (very simplified):

Signal:
owner: -> SignalOwner; opposite outputs

SignalOwner:
outputs: 0..4-> Signal; opposite owner

Criteria -> SignalOwner:

Cause -> SignalOwner:
criterias: Cont.0..* -> Criteria

When I do a EcoreUtil.copy() (note: Signals are NOT contained in the copied section, everything else is) I get:

Cause are copied with their "outputs" Attribute empty (as expected because of bidirectional).

Criteria are not copied at all (this is NOT expected!) together with all its descendants (not shown above).

Is this behavior somehow expected?
What am I doing wrong?
In case it's not expected: where exactly I should debug to see what's going wrong?

Please disregard.
I had mistakenly marked "derived" criterias.
Sorry for the useless noise.
