Post #1758305

@leeloo @Sarnau @mayo @dasdom I don’t know that. All I know is that said someone did add a separate error string for that very case. I assume that it was not expected that it is possible to even try to delete the installed component but whoever wrote that error message had to implement a protocol where `delete()` has to be implemented. Instead of going the extra mile to make sure the delete button is disabled, that someone called it a day.
