[flexcoders] getItemIndex ......returning -1

[kpjj31]

What am I doing wrong. Thanks.

private function getcoursesResult(event:ResultEvent):void{
                
courses = new ArrayCollection (event.result.COURSELIST as Array);
                
var newindex:int = courses.getItemIndex('specific course name');

courses_datagrid.selectedIndex=newindex;
}

arraycollection example...

COURSELIST
+ 0
- 1
  TITLE : 'specific course name'
  DESC : ''
  REQ : ''
