Find criteria must contain at least one sort field value.

I thought this solution looked correct by an expert, but I am getting the error in the subject line. I added the sort, but it doesn't seem to help. Basically I am trying to push the contents of currentAc2Object into ac1 (make it a part of the currentAc1Object). The marketingPromoCode & sourceCode is what I am making the match on.

The data in the two ArrayCollections come from two different data sources, but I want to display them on one row in a datagrid.

Anyways, why does it even fail on sort? I haven't seen one example on google where they were using getItemIndex and it needed to sort. or addItemAt. Whether I have that sort there or not, I get the same error....

ac1.sort = sort;
ac1.refresh();
 
trace("received promo data");
for(var h:int; h < ac1.length; h++)
{
	
   for(var k:int; k < ac2.length; k++) 
   {
   	  if(ac1[h].marketingPromoCode == ac2[k].sourceCode)
      {
      	trace("Match " + ac2[k]); //Returns a ReportVO object
        ac1.addItemAt( ac2[k], h );
        trace("Finish");
         break;
      }
   }
}

Are the ArracyCollections empty? Can you put the sort code inside an if condition that checks the length of the ArrayCollection..

The error might come from this code line:

>>    if(ac1[h].marketingPromoCode == ac2[k].sourceCode)

What kind of object's are 'marketingPromoCode' and 'sourceCode'? Just String's? Or instances of some custom class?

No they aren't empty. and those two fields I am comparing against are strings. I will try putting the sort inside an if to see what happens

Any line beneath these in the stack trace that refer to your own code?

Sorry about the delay. But here is the final answer I came up with.
var currentAc1Object:Object;
					var currentAc2Object:Object; 
					var ac1:ArrayCollection = this._reportProxy.allPromoData;
					var ac2:ArrayCollection = analyticsView.reports;
					var sort:Sort = new Sort();
					sort.fields = [new SortField("marketingPromoCode", true)];
					ac1.sort = sort;
					ac1.refresh();
					sort.fields = [new SortField("sourceCode", true)];
					ac2.sort = sort;
					ac2.refresh();
 
					for(var h:int; h < ac2.length; h++)
					{
					   for(var k:int; k < ac1.length; k++) 
					   {
					   	  if(ac2[h].sourceCode == ac1[k].marketingPromoCode)
					      {
					      	ac2[h].eventLog = ac1[k];
					         break;
					      }
					   }
					}

I just created a property in the Value Object called eventLog, and made it an instance of another value object.
