Steps to reproduce:
1. Create an application (e.g. "my app") and reach step 3 (editing the homepage)
2. Observe that you are in the correct data space ("my app" same as app name)
3. Go back to step 2 (editing the class) by clicking the "Previous Step" left button
4. Click Next to go back to step 3
5. Observe that you are now in the code space ("myappCode") instead of the data space.
