Hi
When being scrolled down, then filtering a larger datasets, where large amounts of data is filtered away, the grid throws an error, where it can't find a record for the given "targetIndex" in the jumpToPosition function in RowManager.js, inside the while loop.
Same error as this post: viewtopic.php?p=116367&hilit=jumpToPosition#p116367
It seems to happen when the grid element goes from scrollable to non-scrollable, but still has some visible records.
