ionic slides shows first image only

[myrsk]

Hello,

Having similar issue to https://github.com/tjoskar/ng-lazyload-image/issues/256

However, since it is a closed issue, I have created a new open one.

However, when i tried to use the same fix. I am getting a runtime error on ionic 3

page.ts - here im getting a debug notice on Subject not found. TS.

imageChange$ = new Subject();

  slideChanged() {
    this.imageChange$.next();
  }

page.html

<ion-slides *ngIf="(item | async).image1" class="image-slider" loop="true" slidesPerView="2" (ionSlideDidChange)="slideChanged()">
        <ion-slide *ngIf="(item | async).image1">
          <img [defaultImage]="'https://www.placecage.com/1000/1000'" [lazyLoad]="(item | async).image1" class="thumb-img" imageViewer [scrollObservable]="imageChange$" [offset]="'100'">
        </ion-slide>
        <ion-slide *ngIf="(item | async).image2">
            <img [defaultImage]="'https://www.placecage.com/1000/1000'" [lazyLoad]="(item | async).image2" class="thumb-img" imageViewer [scrollObservable]="imageChange$" [offset]="'100'">

Uncaught (in promise): ReferenceError: Subject is not defined ReferenceError: Subject is not defined

Hi @myrsk, Have you imported Subject from rxjs? Like this: import { Subject } from 'rxjs/Subject';?

[myrsk]

@tjoskar unfortunately, since I couldn't get it to work for some days, I had to remove it and used a different approach.

I will try this though, not sure 100% if i did import.

Thanks.

@myrsk, I see, let me know if it doesn't solve your issue.

Hi @sabiridwan, Do you get the same error, ReferenceError: Subject is not defined ReferenceError: Subject is not defined? In any case, please open a new issue and I will try to help you.
