[Chameleon] extent history

[Kevin Flanders]

I have added the ExtentHistory widget button to my navigation toolbar, and get the following error:
   
  Notice: Only variable references should be returned by reference in C:\ms4w\apps\chameleon\htdocs\WidgetManager.php on line 265
   
   
   
  Am I missing something?
