Ionic-framework: ion-slides Cannot read property 'hasAttribute' of undefined

[markisme]

when use *ngFor ion-slides, get this error when start the page.

Uncaught TypeError: Cannot read property 'hasAttribute' of undefined

And in swiper.ts ,I see that
https://github.com/driftyco/ionic/blob/master/src/components/slides/swiper/swiper.ts#L206, did it's because the acitveindex is undefined,because when there no data in modal.the swiper is still no slide???
By the way , why the ion-slides remove the options, and use this.slides.attributes=value to modify some hidden options. The options of swiper is awsome, and use very well for us to custom the slides.

I have the solution:
Do like this

<ion-slides *ngIf="slideData && slideData.length" autoplay="5000" class="slideroption" pager="true"   loop="true" speed="300">
      <ion-slide   *ngFor="let slide of slideData">
                <img src="{{slide.imag}}" />
          </ion-slide>
    </ion-slides>

Thanks for the solution.
However the developers should definitely take a look at this case, it makes no sense that an empty array is illiterated.
