[flexcoders] Creating an ArrayCollections dyamically

[Wally Kolcz]

I have a web service that send back my column names and data in 2 seperate 
collections. I would like to put them back together as one arraycollection. I 
created a method that takes the total number of record, the Arraycollection of  
column names and the arraycollection of data. I would like to get it back to 
where I can say myData.getItemAt(0).ProjectName

Here is what I have so far, but trying to create an object name dynamically is 
causing an error. Any ideas? Thanks!

public function convert(total:int, columns:ArrayCollection, 
data:ArrayCollection):ArrayCollection {

            var AC:ArrayCollection = new ArrayCollection();

            //Loop over the total number of records
            for (var r:int = 0; r < total; r++){
                //Create a new row for the ArrayCollection
                var row:Object = new Object();
                //Loop over the columns and data
                for (var i:int = 0; i< columns.length(); i++){
                    row.column[r][i].toString()=data[r][i];  <----Error on the 
'row.column...'
                }
                AC.addItem(row);

            }

            return AC;
        }
