We're running an instance on AEM 6.4.6.0. The authoring interface does not load anymore when attempting to author editable templates. It shows the following JS error: TypeError: ns.ContentFrame._EditableUtils is undefined Using the debugger, I can see that this function is affected, which seems to be Granite built-in:ns.ContentFrame._EditableUtils.shouldFilterEditable = function (editable) { return !!editable }; The problem occurs with and without minification. Any ideas?
