Subject: [PATCH] Bug 27837: Always pass permanent location from items editor
 if it was defined

By always passing permenent location from the items editor, we can know
if permanent location was defined in the framework. This means we can
know if we should update permanent location independently of location
even if permenent location has an empty value.
