After creating an openshift user using default host, the view properly recognizes your user, your domain, and your application. When right-clicking the application and selecting 'import application', the wizard shows it is unable to find the application. The domain combo box is also empty. The error message indicates a missing application.
All of these symtpoms are just hiding the true cause: the user's connection cannot be found because it is using the default host, and the wizard is looking in a map for a complete connection url, when only the truncated connection url exists.
Make sure this gets into both branches.
