... for ALL my services.

... manually it is.

A feature? but wouldn't a better, not to mention obvious, feature allow the updating or refreshing of the service response to match that of the database columns? I have a similar problem whereby i rename a column but the service response shows only the old name.

Yep, it's happening to me too, in Chrome. Unable to delete a mapping. It worked yesterday mind you. Don't really want to clear cache and cookies, restart browser, restart machine, delete service, in order to fix it. Just want to remove a mapping.
