When the notifications portlet is undeployed, it would be nice if there was a more graceful way to handle the poller NPEs

• Type: Feature Request

• Resolution: Unresolved
• Affects Version/s: None

• Component/s: Social Office User Bar (Dockbar), Social Office User Bar (Dockbar) > Notifications
• Labels:
  • notifications_so

Currently when you uninstall Social Office (or sometimes when you install Social Office) and your browser is open to a page that has the notifications portlet on it, the console will show NPEs until the plugins are completely undeployed. Presumably, the poller is still running in the background as the undeploy process is running concurrently, causing these NPEs. I was wondering if there's a better way to handle these exceptions so that other people won't be lead to think that something is broken or wrong.
