iosEstimatedRowHeight crashes iOS app

[tucazinul]

Hi,

I have two ListViews on different routes, to which I set iosEstimatedRowHeight = 0 and rowHeight = -1. The first time I reach those pages everything works great. The second time however (Page 1 -> Page 2 -> Page 1) it crashes with the message:

ns-list-view: ViewReference not found for item 1. View recycling is not working

On android everything works and also on iOS if i remove the iosEstimatedRowHeight property. But I need that property to avoid scroll issues.

This is how I set the properties in the components:

onListViewLoaded(args): void {
  this.listView = args.object;
  if (isIOS) {
     this.listView.ios.allowsSelection = false;
     this.listView.rowHeight = -1;
     this.listView.iosEstimatedRowHeight = 0;
 }
}

The html it's kinda like this:

<StackLayout height="100%">
  <StackLayout class="body">
        <ListView separatorColor="#fafafc" (loaded)="onListViewLoaded($event)" (loadMoreItems)="loadMoreItems()" [items]="itemsArray" >
          <ng-template let-item="item">
                <Label textWrap="true" class="title" [text]="item.title"></Label>
          </ng-template>
        </ListView>
  </StackLayout>
</StackLayout>

package.json:

Please ask for more details, I don't know what else could be useful.
