LPS-45321 - When selecting a new scope in Control Panel we should refresh the portlet being displayed

Hi @jonmak08,

Attached is an update for https://issues.liferay.com/browse/LPS-45321.

I think the issue with my previous pull (https://github.com/jonmak08/liferay-portal/pull/683) was I didn't use a unique enough name for the URL string.

Please let me know if there are any more issues.

Thanks!
