Moving from DataObjectManager – GridFieldRecordEditor, GridFieldRelationEditor and usability issues

Recently I’ve been working a lot with the SilverStripe CMS/framework written in PHP (as one could undoubtedly deduce from my earlier post). The context involved porting a custom application from SilverStripe 2.4 to 3.1. Naturally this also involved dealing with the formerly used DataObjectManager module and 3.x’s new ORM and GridField components.
