If multiple workbench subapps are open simultaneously, e.g. Security app + Contacts app = 5 Workbenches; then they are all updated when performing a repository operation in one of them.

ContentChangeEvents are fired on admincentral event bus, and are then listened to in the ContentWorkbenchPresenter(s). The problem is that this handler also refreshes selection and updates action bar preview, so it will try to do it as well in inactive subapps, whose selection should be left untouched, and which might even operate on a different workspace.
