Description of problem:
If user is going through the add permissions wizard after step #1 and clicks back on step #2, s/he seems to still be in the view for step #2. Clicking back again returns user to step #1

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Create new role
2.  Chose role from roles view
3.  Chose global permission and hit Add permission
4.  Chose a permission and click the "Next" button; note that the Name and Description fields appear
5. Click the back button.  Note that the same view exists
6. Click the back button again.  Note that we've returned back to the initial view  

Actual results:
 One step forward, two steps back :)

Expected results:
Proper navigation in wizard

Additional info:
* It seems that temporarily I was no longer able to no longer navigate any roles after doing this, but that might've been something else.
* Please do not get Paula Abdul stuck in your head while working on this bug.
