When creating an OpenShift application, after setting the name, application type and pressing the next button you are greeted with a screen to select the cartridges to be embedded into the application.

The error here is that the 'back' button is still allowed to be pressed. Pressing the back button will generate the attached error.This occurs because when the user presses the next button mentioned above, the application is created, so upon pressing the 'back button on the embed cartridges screen the wizard seems to become confused since if the user could go back and then press 'next' again to get to the embed cartridges screen, it wouldn't work unless the application name was changed.
