angular: Router resolved data does not persist in ActivatedRoute data after navigation

so can you explain why I can access the data defined in the data property of the parent without calling parent.data

it’s the actual bug. and u have access only on initial navigation. or may be it’s a feature. Need feedback from Victor

http://plnkr.co/edit/NgDlGWjrMQC8pMVzSVkA?p=preview this is the correct plunker and expected behavior.

Did he write anything about data availability in his blog? No.

@michaelchiche it is not hack, it is the way you can access data from parents, you can write simply function that go upward to any level. ‘Parent’ is a public property of route and snapshot. I didn’t see any reasons do not use it. More then this it is the right way to get data from parents. How do you think to implement all data at all levels? Let say we have n levels and all levels resolves to data, in first level we have one property of data, next level adds one more, and finally we have n(n+1)/2 properties and n^2 complexity. Of course we can use prototyping but this is the same like parent property.

function getParentData(snapshot:any, level:number) {
  var ref = snapshot;

  while (level--) {
     ref = ref.parent;     
  }
  return ref.data;
}
