Problem

User can mark assigned to task language resource as writable.

In this case after task is finished segments from task will be reimported into language resource.

But user can assign language resource of sub language to major language of task and vice-versa.

In this case even if task has DE as source and EN-GB as target on reimport to language resource with de -> en-us or de-de -> en and etc it segments will be saved with language pair of language resource.

Solution

Popup warning window for user on making language resource writable in task assignments.
