Hidden grid data manipulation

Flow
1

A grid is created hidden, while it is hidden its columns and data is recreated. Once the grid is set to visible, the following is shown in the browser:

(TypeError): cannot read property ‘a’ of undefined.

Attached a minimal example including the accompanying pom file. To reproduce, press the change data button and then show/hide.

Thank you,

Can you test with Vaadin 14.0.5 as well? I wasn’t able to reproduce the issue there.

Hi Olli,

Thank you so much for testing! You are right, 14.0.5 worked correctly. The problem was in version 13.

Thanks,
Razvan
