Filter for “qualifier does not exist” doesn’t work

[lucaswerkmeister]

1. Add a filter for any statement, e. g. “instance of: Wikidata”.
2. Add a qualifier filter for any property, e. g. “end time”.
3. For the qualifier value, select “does not exist”.
4. Click “show results”.

Expected: results show up. (In this case, 0 results, but something should still happen.)

Actual: Nothing happens (no WDQS embed), and there are two errors in the console:

1. When you select “does not exist”:

   [Vue warn]: Error in callback for watcher "valueType": "TypeError: specialValue.classConstructor is not a constructor"

Thanks for reporting this! The "does not exist" special value isn't implemented yet unfortunately. I should probably document this somewhere and make sure that it doesn't completely crash. It's all still a little prototype-y and rough around the edges in a few places.

Ah, okay, I didn’t know that :)
