Thanks. I think we should fix this at the root cause of the issues instead.

Thanks. This is a good change. Would you please add a test for the change to the lib/resource.rb class? The view does not need a spec.

@gr8bit I would like to add this to the 5.0 release as this breaks for all sites not having the translations in place, but a browser with non-English locale

Thanks
