title: How can You refresh a vaadin grid after data change
body: <p><strong>How can You refresh a grid, when some new row was added to its datasoruce container or one of its rows has been edited?</strong> </p>
  
  <p>I have tried the hacks written about here (<a href="http://www.helpsforcoder.com/code/31861375-vaadin-refresh-grid-after-row-modification.html" rel="nofollow">http://www.helpsforcoder.com/code/31861375-vaadin-refresh-grid-after-row-modification.html</a> ) and here (deleted link to malicious advertisement) but with no positive result. I add / edit the row in a separate subwindow that 'pop-ups' over the view, where the grid, that should update its contents, is placed.</p>
