hi, maybe someone can help me. i've two pages. one with a list of buildings and another with a google map whith all buildings marked on the map. if i switch the first time from the buildings list page to the map page all is working fine. however, if i switch back to the buildings list page and open the map page a 2nd time my Event subscribe functions calls twice - the service which fire the event just fire the event once. i've also added an event unsubscribe on the ionViewWillUnload hook.
