Subject [jira] [Created] (RAVE-331) Error when trying to upload a duplicate gadget url to widget store

Error when trying to upload a duplicate gadget url to widget store
------------------------------------------------------------------

                 Key: RAVE-331
                 URL: https://issues.apache.org/jira/browse/RAVE-331
             Project: Rave
          Issue Type: Bug
    Affects Versions: 0.5-INCUBATING
            Reporter: Anthony Carlucci
            Priority: Minor


How to Reproduce
--------------------------
1) Login to Rave as any user
2) Upload a gadget to the widget store - verify it was added successfully
3) Go back and try to add the same gadget url again
4) You will see the standard "rave has suffered a brief meltdown" page

The issue is that the DefaultWidgetService.registerNewWidget function returns a null Widget
object if it finds the URL already in the system.  The RavePermissionEvaluator.hasPermission
functions are not properly dealing with potential null objects and thus a NPE is thrown.

How to Fix
----------------
1) Improve the RavePermissionEvaluator.hasPermission methods to check for and safely handle
possible null objects.
