Description

Hello everyone;

I have a nativescript angular project that has a few DateTimePickerFields inside of some ListViews that behaves unreliably on iOS (android is completely fine).

Essentially, if i have a ListView with 3 separate DateTimePickerFields, and I tap&set the DTPF at position 0, a random other DTPF will get the value.

My knowledge with Nativescript & Angular is limited; so if I'm doing something wrong or if anyone has some tips/tricks i would be greatly appreciative.

(demo of app and issue)

(inputs on item of index 0 usually work; once we touched DTPF index 2, the value goes in DTF index1 and yeah...)

(simplified code)

PMSubDetailsMooringsComponent.html

  <ListView
      [items]="displayItems"
      [itemTemplateSelector]="selectItemTemplate"
    >
      <ng-template
        let-item="item"
        let-i="index"
      >
        <FlexboxLayout
          flexDirection="column"
        >
          <Label
            [text]="'index:'+ i"
          ></Label>

          <DateTimePickerFields
            [(ngModel)]="item"
            (touch)="yes(i)"
          ></DateTimePickerFields>
       </FlexboxLayout>
     </ng-template>
</ListView>

PMSubDetailsMooringsComponent.ts

export class PMSubDetailsMooringsComponent extends PMBaseComponent {
    displayItems: Date = {[null,null,null]}        
    index = -1;



 yes(i) {
        //just using this to display what value got touched
        this.index = i;
    }
}

Research direction

Start with PMSubDetailsMooringsComponent.html and PMSubDetailsMooringsComponent.ts, focusing on the ListView, itemTemplateSelector, and DateTimePickerFields bindings. Reproduce the behavior on iOS using the supplied three-item example, then compare the touched index with the updated value. Done means the selected field consistently receives its own value, with the behavior verified on iOS and Android.
