after this..

 ngOnInit() { 
this.sub = this.route.params.subscribe(params => {
  let id = Number.parseInt(params['id']);
  console.log('getting person with id: ', id);
  this.peopleService
    .get(id)
    .subscribe(p => this.person = p);
});

}

why does

console.log(this.person);

return undefined? code my code is based on this It all works fine when I use it in the html, for example

{{person.id}}

and it works fine in my component.ts when I pass the data to a Material dialog using 

data:this.activity

I've added 

@input person:Person;

What do I need to do to be able to console.log(this.person) ?

The reason I'm asking is curiosity and also I need use patchValue on a reactive form and I get undefined if I add 

 this.personForm
       // .patchValue({name:this.person.name});

I rewrote the subscribe line 

         .subscribe((response) =>{
          this.person = response; 
          this.personForm
         .patchValue({name:this.person.name});              
          });

and it works but probably not the nicest way to do it?

  • Not enough context to establish what is going on, try moving your logic into ngAfterViewInit() instead of ngOnInit(). Maybe your data is not ready during ngOnInit() – adentum Jul 12 '17 at 10:46
  • @echonax thanks that is pretty much it – vtechmonkey Jul 12 '17 at 12:29
  • @echonax I had it after `this.peopleService .get(id) .subscribe(p => this.person = p);` – vtechmonkey Jul 12 '17 at 12:34
