To achieve what you need with the same architecture you can use the $rootScope to pass the data between your controllers. Here is the updated code :
(function(angular) {
'use strict';
function someOtherTabPageController($scope,$rootScope) {
var ctrl = this;
//do some work with the passingObject
alert($rootScope.passingObject);
}
angular.module('heroApp').component('someOtherTabPage', {
templateUrl: 'someOtherTabPage.html',
controller: someOtherTabPageController,
bindings :{
passingObject: '='
}
});
})(window.angular);
(function(angular) {
'use strict';
function HeroListController($scope, $element, $attrs,$rootScope) {
var ctrl = this;
// This would be loaded by $http etc.
ctrl.list = [
{
name: 'Superman',
location: ''
},
{
name: 'Batman',
location: 'Wayne Manor'
}
];
ctrl.create = function(hero) {
ctrl.list.push(angular.copy(hero));
};
ctrl.updateHero = function(hero, prop, value) {
hero[prop] = value;
};
ctrl.deleteHero = function(hero) {
var idx = ctrl.list.indexOf(hero);
if (idx >= 0) {
ctrl.list.splice(idx, 1);
}
};
$scope.passingObject = ctrl.list;
$rootScope.passingObject = ctrl.list;
}
angular.module('heroApp').component('heroList', {
templateUrl: 'heroList.html',
controller: HeroListController,
bindings: {
onCreate: '&'
}
});
})(window.angular);
