Hi Martin:
Thank you for your quick response. I was initially updating the entire table, but that was causing me to lose focus from the drop-down menu in which I made the selection. Also, my hope was that I could update as few row items/components as possible, thereby expediting the table-refresh process. When you mention 'Wicket's Event System', are you referring to inter-component events, like the example portrayed here: http://savicprvoslav.blogspot.com/2012/06/wicket-15-inter-component-events.html Regards, - Ephraim -----Original Message----- From: Martin Grigorov [mailto:mgrigo...@apache.org] Sent: Tuesday, September 09, 2014 12:10 PM To: users@wicket.apache.org Subject: Re: Referencing DataTable rows within the table column header Hi, Why don't you update the table itself ? This will update all its children components too. Otherwise I'd use Wicket's Event system to send a notification to all interested parties.
