There is already a post on the forum somewhere but we haven't been able to find it again.
In Version 9, if an XMLPackage has an error a "this page has an error" message is displayed. Nice for the customer! And the error is logged in Admin: Configuration -> Maintenance -> View System Log. Nice for production.
How is this behavior turned off in a development environment so that errors are seen directly on the XMLPackage page?
Thanks!
