Description of problem:

When creating a new role, a user is able to initially select one "Read?" checkbox in resource permissions.  A warning pops up, and then this box is unable to be reverted.  Subsequent attempts to check any other read checkbox fails.

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


How reproducible:


Steps to Reproduce:
1. Administration > Roles > New
2. Choose one of the items in Resource Permissions (i.e., "Manage Alerts"), check/double-click the "Read?" checkbox.
3. Note the warning that appears
4. Attempt to uncheck this box.
5. Attempt to select any other "Read?" box for other permissions  
Actual results:

* Box can be checked but subsequently cannot be unchecked


Expected results:

* I don't think we're allowing someone to explicitly select the read box -- as the UI warning notes, "Read access for the Manage Content permission is implied and cannot be disabled." But this -- and most others -- can be selected at least initially, and not unselected. 

Additional info:

Please note that the "Configure" checkbox appears to be a different case.  It can be selected/unselected multiple times and no warnings appear.  However, it is true that once the actions listed in steps 1-5 above are taken, the Configure checkbox can no longer be selected.  This may well be a completely different bug.
