Component sharing variable for some reason


Component sharing variable for some reason

wish help you to fix your issue I'm pretty sure it's because you're defining steps : [], in your component definition. Since an array is an object in JavaScript, you're basically giving ALL components a reference to the same object, so it becomes shared across all instances of the component class. In standard OOP, you're making a class variable that is essentially global.
To fix this, change steps : [], -> steps: null, and then create an init method that initializes the steps property for the instance:
code :
initSteps: function() {
    this.set('steps', Ember.A());
}.on('init')

I hope this helps you . 'Transient' explicitly means 'non-shared', so what you are asking is conceptually the wrong thing to do. The correct solution is to register Shared as a Singleton instead of Transient:
code :
container.Register(Component.For<Shared>());
container.Register(Component.For<Shared>().LifeStyle.Transient);

var r = container.Resolve<Shared>();

container.Register(Component
    .For<IFoo>()
    .ImplementedBy<Decorator>()
    .DependsOn(new { resource = r }));
container.Register(Component
    .For<IFoo>()
    .ImplementedBy<Decorated>()
    .DependsOn(new { resource = r }));
container.Register(Component.For<Shared>().LifeStyle.Transient);
container.Register(Component.For<Shared>().Named("shared"));
container.Register(Component
    .For<IFoo>()
    .ImplementedBy<Decorator>()
    .ServiceOverrides(new { resource = "shared" }));
container.Register(Component
    .For<IFoo>()
    .ImplementedBy<Decorated>()
    .ServiceOverrides(new { resource = "shared" }));

help you fix your problem I have component where I set the value of Boolean variable into the service, and another component where I have subscribed to the same service. , If you use providers in @Component like this
code :
@Component({
  selector: 'navigation',
  templateUrl: './navigation.component.html',
  styleUrls: ['./navigation.component.css'],
  providers: [SharedService]  // <-- here
})

With these it helps It doesn't work because when you emit value inside subject the underlying component was suppose to listen wasn't loaded. That component is getting loaded after router.navigate called.
You should consider using BehaviorSubject instead of Subject, as BehaviourSubject persist last emitted value. Also it emits last/inital persisted value when someone subscribes to it.
code :
//it needs initial state while registering it, so passed false
private isSuccess = new BehaviorSubject<boolean>(false);

I wish this help you You are breaking the contract, so unfortunately you get whatever you get. And since it's not a supported use case you sadly can't expect it not to change in different React versions either.
React expects a pure functional component to be, well, a pure, functional, component (referentially transparent, no side effects). You are mutating your props, which as I said is not supported (this seems to come up a lot on github issues on the React repo).

Hope that helps From what i can see in the limited amount of code you shared, it would seem you are trying to get the items before the http get call finishes and saves the data. I think a better design pattern would be to make the GetItems() function also an observable or promise, and check if the data is there, if not call the http get call, and once that completes send the data back to the different components that need it.
