Misbehavior in the external gadget field

Problem:

When you try set some parameter in the Gadget Feeds tab or Gadget Whitelist tab, instead of just refresh that tab, it'll back to original tab.

Steps to reproduce:

• Go to Confluence Admin > External Gadget
• For example, go to "Gadget Feeds" tab and add "http://jira.atlassian.com/rest/gadgets/1.0/g/feed" and hit add.

You'll see that will apply that parameter, and will be back to the original tab, in this case, "Gadget Specifications"

Workaround:

Just go to that specific tab.
