Using Ionic3 to implement large list scrolling with virtualScroll. I added a vertical slider (input range) linked to a function using Ionic3

  • this.content.scrollTo(0, yVal, 1000)

to scroll back and forth but if I scroll too far ahead in the list, I get the error

  • ERROR TypeError: Cannot read property 'scrollTop' of null

I played with the time parameter but nothing seems to make a difference. My list has 10k items and if I scroll one step at a time (1%), everything is fine. But if I try to go all the way to 50% of the list, I get a blank output with the above error.

What am I doing wrong ???
