As Magnolia 5.4.11/5.5.2 restores support for upload fields with i18n. It now appears that the mgnl:resource nodes created with i18n suffix are not properly accounted for.

• First, it appears I18nNodeWrapper no longer delegates #getNode to the I18nContentSupport, as it does for properties, and as it did between 4.5.2 and 4.5.8.
• Once we sort this out, we should ensure link generation gets it right.

Thanks for reporting, tomwespi:

I tested with 2 languages (de/en), created an i18n file upload field, uploaded 2 files (test_de.pdf, test_en.pdf) and created a link to them with cmsfn.link(content.file).

It creates following, wrong link:
/test/main/0/test_de.pdf
/en/test/main/0/test_de.pdf

The files are saved correctly under the node
/test/main/0/file/filename ...
/test/main/0/file_en/filename ...
