duplicate lines after sort by column

I am seeing a strage error where a row is duplicated (and the duplicate is taking the place of an actual row on the screen) after sorting by a column in my application. I am on Vaadin 7.6.7. Has anyone seen anything like this before?


Hi, I don’t remember seeing such an issue. If you would be able to attach a simple reproducible example, perhaps I could look at it at some point.

This was an application issue that I finally figured out. Not a Vaadin problem.
