TYPO3 Core

Yes. We do have the same issue. It's completely confusing for our editors. I would highly appreciate this little change!

I tried to work on a patch here, but it came out that this is not as easy as it sounds.

Background:

Localizations for inline items are generated through the TYPO3 DataHandler in DataHandler::inlineLocalizeSynchronize(). Here, all inline items are fetched and regardless of, if a localization for a record exist or not, (DataHandler::localize()) is used to create a localization. The shown error message is generated in DataHandler::localize(), which is widely used in DataHandler to create translations. So it might be correct to show the error for non-inline records, but for inline records, the error is useless.

Changing the error message to e.g. a warning is also not that easy, since again the scenario of inline vs. non-inline record has be be respected.

I think it would be best, if DataHandler::inlineLocalizeSynchronize() will check, if a translation for a record exist and if so, not tries to create a new translation for it. This would result in those error messages not being shown at all.
