I am having a weird issue with an External Content Type ID column when added to the view causes the view to drop into SP2010 branding (with new button at the bottom). When I remove the ID from the view it has the SharePoint 2013 branding with the "add new" link and view selector. I have another list based on another ECT and it doesn't exhibit this behavior. The Monthly Totals ECT with the ID column I am having issues with but the Assessment ECT works with the record ID . ID column is a primary key, int, not null value in the DB. Anybody have ideas?
This is where it works without the ID column.
This is 2010 SharePoint branding due to adding the ID column. It is missing the new item textbox as well as the view picker. The add new green cross is at the bottom
