Grid Filter/Selection Error

Hello,
I have a list of items in a vaadin grid and by selecting a row detailed information can be displayed next to the grid. Furthermore I can filter the grid to find specific entries.

Sometimes after filtering the grid the element can not be selected anymore and this client-side error appears:

The error is not replicable and it seems like it appears randomly.
Do you have any idea what is causing this error and how I can solve this problem?
