Empty rows appear in Grid when scroll back in the condition of loading data

Vaadin 6 / 7 / 8
1

I am using the lazy loading feature of the grid. And it will load 10 items from DB every time when I scroll down.

But I found one critical issue now and I have no idea how to resolve. It will show empty rows if I scroll back.

The reproduce step is:

  1. prepare amount of data, like 500 items.
  2. scroll the grid down.
  3. scroll back.

does anybody know how to resolve this?

Hi Yuri,

I have the same issue. Using lazy loading with Vaadin 8 (8.x.x), the grid shows empty rows when I scroll down, but only after applying some filter.
Did you fix your issue? Any ideas?

Thank you very much

I don’t know how to resolve this.

We also see some empty or overlapping rows when we scroll our Grid which is loading data at the same time. It looks like a framework issue for us (happens in latest Vaadin 8 grids, also in older versions). Is this a known issue and are there any known workarounds and plans to fix it?

I have updated to the last Vaadin 8.x version (8.10.2) and some vaadin-spring components to the last version I can run, but the problem doesn’t disappear.
Some news about your projects? Any solution?

Do you know if someone has published any bug related to this situation?

Thanks!
