Frank--the code I posted was just a snippet from one of our projects.
It is not intended to work in your particular scenario. You more than
likely do not have a configVO class (if you are a beginner, you
probably are not even using the VO pattern). Furthermore, if your
data is not XML-based (e.g. you are using Webservices or Remoting),
this solution may not even apply.
But, assuming you are using xml-based data:
private function getResult( event:ResultEvent):void {
var dp:ArrayCollection;
//somehow determine if you have only one row by introspecting
data--this will be specific to your situation
if( <one row test comes here...> ) {
dp = new ArrayCollection();
db.add( event.results as ObjectProxy );
} else {
//mult rows in result set
db = event as ArrayCollection;
}
}
