I'm trying to use @ViewChild to get the DOM element that I need. I have the following component that describes my problem:
import Component, ViewChild, ElementRef, OnInit, Input from "@angular/core";
@Component(
selector: 'some-comp',
template: `
<input
#myInputOut
type="text"
class="google-place-input"

</required-input>
</span>
<div class="row form-group2 required">
<label class=" col-3 control-label" for="street">label:</label>
<input #myInputIn class="col-7" id="someid" placeholder="Type to search.." /></div>
`
)
export class someClass implements OnInit
@ViewChild('myInputOut') myInputOut: ElementRef;
@ViewChild('myInputIn') myInputIn: ElementRef;

private element2: HTMLInputElement;
constructor( private databaseService : DatabaseService,
private router : Router)
ngOnInit()
this.element = this.myInputOut.nativeElement;
this.element2 = this.myInputIn.nativeElement;
For some reason myInputOut returns properly but myInputIn returns undefined.
How can I solve this?

Looks like you are commenting the input or at least started to
<!-- <div class="row form-group2 required">
<label class=" col-3 control-label" for="street">label:</label>
<input #myInputIn class="col-7" id="someid" placeholder="Type to search.." />

You will be able to access ViewChild queries only inside ngAfterViewInit().
It's not available in ngOnInit() hence you are getting undefined.
