Ticket #31395
I am unable to correctly add or edit External Objects on an older app in the development interface. When I click the 'Locations' dropdown as I'm editing the External Object, it is blank.
Examined customer's application. The issue here is because of the template being used for this older application. The 'Web 2.0 Single Record Maintenance' template that he was using has been deprecated since the Dec 20th 2012 update, and replaced with the 'Single Row Maintainer' template. Note that applications that use deprecated templates will continue to work and run as-is, however only should you want to edit the application's specifications will it then need to be switched to the appropriate supported template. You will need to change the template to the 'Single Row Maintainer' template and recompile the application.
