Summary: this broke somewhat recently. the new availabletranslationsmodel's rowcount is always 0 on a completely fresh system with no language preference set. this is because the actual available languages list is only compiled in its ::setSelectedLanguages function. this function was however never called. this resulted in the kcm thinking there are no available languages and thus making it impossible to actually add one by disabling the button and having an empty view even if the button wasn't disabled. previously this was a single model, from what I can see, and that was incorrectly ported. where previously the setSelectedLanguages was only called on one model we now need to call it on all models to properly propagate the language information. (the reason it works this way is because available languages kinda need to include already selected languages for consistency; even when the kcm technically didn't find them available) Test Plan: - make new user - start kcm - kcm DOES NOT show infobox 'no languages installed' and the add languages button is enabled - clicking the button gives a list of languages - adding one works as well Reviewers: sitter Subscribers: ngraham, plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D15115
