I have set my i18n languages options so that the interface and node language can be changed independently.
Since I installed node translationship the references shown in the autocomplete text field, are in the interface language, not the node language.
The "noderef" view shows the nodes in all languages. I have added the i18n negotiation filter, but then only the interface language is selected.
The only solution I have for the moment is to enable the multilingual option:
"Switch interface for translating"
