Description

Hi I in my grid I want to make a link reference (for each row) to other page, the link is build of row.entity data of the grid (so it's different and unique for each row), the problem is when I have scroll implemented (by default) for some rows (when scrolling down) then row.entity is not the same as the row it supposed to be, but when I display the hall data (by invoking function that gets the data.length and auto-resize ui-grid) each row.entity is the same as it must be in the grid. Is it a bug or I need to change something in the gridOptions? Thanks.

Research direction
Investigate the row entity caching mechanism in ui grid, particularly the scrolling and virtualization logic. Look at the grid rendering code in the repository for how row entities are mapped to visible rows during scroll. Check if there is a mismatch in the row identity when rows are recycled.
