Change Details

1. Go to https://www.wikidata.org/wiki/Q428581 (Possession book) 2. at the bottom of Statements, click [add] 3. choose publication date, enter 1990 4. click [add reference] Result: nothing happens (is it a bug that the UI doesn't show any error?). If you look in developer console, there's an error "Error: Required option not specified properly". I found from `?debug=1` that the error is in jquery.wikibase.referenceview.js line 93 because `this.options.statementGuid` is null. It happens in Firefox and chromium. Maybe I'm meant to save the statement first? But if I click Save, I get TypeError: edittoolbar is undefined btnSave = edittoolbar.getButton( 'save' ), referenceview.js (line 73, col 5) and again, no error shown to user.
