i have controller wraps ui-router , control flow (like menu bar). when user press on menu item, there function changes ui-router state , broadcast event inner controllers. every inner controller inside ui-router can listen , act event. inner controllers making validation on event if validation fails cannot undo state change. idea how solve problem? thanks update : using ui-router $statechangestart event approach still incomplete. problem is, main controller hosts ui-router , menu bar has progress bar. main controller registered $statechangestart , taking care of progress bar, child view register event preventing default. means controllers in inconsistent mode. main controller has took care of progress bar , view did not changed. please advise the ui-router issues $statechangestart event. your controllers can use event.preventdefault() prevent transition happening. $scope.$on('$statechangestart', function(event, tostate, toparams, fromstate, fromparams
