Problem

Sample:
Task with source-lang: de-DE
and target-languge: sr-Cyrl-RS

Language Resource (e.g.) Microsoft:

• MI_de_sr
• MI_de_sr-Cyrl

a language-resource for sr-Cyrl-RS can not be defined for Microsoft, because its not supported.

If I want to pretranslate the above task with the defined language-resource I wqould expect, that:
MI_de_sr-Cyrl would by the first choice and MI_de_sr the second one.
But:
MI_de_sr-Cyrl is not detected as valid resource.

Can also be reproduced with the "Dummy Pseudo Translator". See Screenshots

Solution

The problem seems to be the 3-parts language. Fallback should be
sr-Cyrl-RS
sr-Cyrl
sr

but it looks like when for the first level "sr-Cyrl-RS" (the "complete name") no match can be found, if falls back directly to the fallback of the "generic" language "sr"
So there should not only be one fallback, but a fallback-chain as described above.

This error is the problem there:

and maybe there??
