Flex :: Flash - Converting IDs To Account Name

I am using Adobe Air to get data from SalesForce, and present it in a datagrid. I am using a query to get the data, and then put it into an arraycollection that is bound to the datagrid, this works correctly and the data is displayed. The problem is that I want to convert the Account Id in the Event to show the account Name. To do this I am using the following code:-

_serviceWrapper.query( "Select * From Event order by StartDateTime asc", new mx.rpc.Responder( eventQueryHandler, faultHandler ))}
protected function eventQueryHandler(qr:ArrayCollection):void {
var acctIdss:String = "";
for each(var contact:DynamicEntity in qr) {
[Code] .....

This works and displays the Account Name, the problem is that when I use this script and then Sync Changes to SalesForce all the records that have been displayed are identified as needing to be syncronised even if they have only been displayed. If I skip the function eventQueryHandler, and link my query to the OnQueryResult function then there is no problem, but only the Account Id can be displayed. How can I stop Air marking these records as having changed, or is there a better way to achieve this?
