Hello,
I have this error on my project

org.eclipse.scout.rt.shared.extension.IllegalExtensionException: Contribution or inner class [com.test.apps.ext.client.DesktopExtension] is not allowed within the owner [com.test.apps.client.Desktop]. If this is an ordinary inner class, extract it to its own file.

Did any one experienced such error ?

I created a hello world scout project and wanted to extend it by adding a new outline.
So I created a client server shared project and in client I replaced the Desktop with Desktop Extension pointing to Desktop and it contain a new outline.

Kind Regards

Your class com.test.apps.ext.client.DesktopExtension must not be an inner class of com.test.apps.client.Desktop but instead be defined in its own .java file. Make sure to not forget to register your extension via IExtensionRegistry#register. There should be no need to replace the desktop directly when working with a desktop extension. When having a Desktop class anyway, you could define your outline directly in that class too instead of using a desktop extension.

Regards
Stephan
