New to Ionic here, just love it. SuperSample is fantastic… but I’m a bit lost and don’t know where to turn to at this point.
When using scrollTo on a virtualScroll content to jump far ahead in a large list, the list goes blank and the following error is generated
vScrollSegmentRangePage.html:25 ERROR TypeError: Cannot read property 'scrollTop' of null at VirtualScroll.scrollUpdate (virtual-scroll.ts:714) at SafeSubscriber.schedulerFn [as _next] (event_emitter.ts:121) at SafeSubscriber.__tryOrUnsub (Subscriber.ts:254) ... at EventEmitterProxy.EventEmitter.emit (event_emitter.ts:80) at ScrollView.scroll.onScroll (content.ts:441) at ScrollView.setScrolling (scroll-view.ts:74)
scrollTo is called from a function bound to a vertical slider/range.
Sample code can be found at https://stackblitz.com/edit/ionic-list100k-segment-index
The current list has 10k items. Scolling from the navigator page is fine as it scrolls gradually.
But when I use the slider to go to the middle of the list for example, I get the above error, the list goes blank and never recovers.
Am I doing something wrong ?
Am I missing some parameters ?
Is this a bug ?
Tx for any input.
