The error message reads...Undefined placeholder ‘Layouts.DesktopLayout.Content’ (noplaceholder ‘Layouts.Desktop.Layout.content’). / Form call argument / Page ‘Runtimeinstances’ / Administration I am new to Mendix and to app development. I need to get this app finished and uploaded today for a client. I need help in resolving this error message if possible. Thank you, Tony Young
There is an issue with the layout your app is using called DesktopLayout. There should be a placeholder in the layout called Content that is not there for some reason. If you edit the DesktopLayout and put a placeholder somewhere on the layout called Content, you should be good to go.
