How do you do use cfajaxproxy with setSyncMode()?

Question

I found lots of examples using asynchronously, but I can't find any examples using synchronously? Does anyone know how to do that?

Using the adobe example below, how would you change from asynchronously to synchronously? I added in setSyncMode(), but doesn't seem to work.

            // Use an asynchronous call to get the employees for the 
            // drop-down employee list from the ColdFusion server.
            var getEmployees = function(){
                // Create an instance of the proxy. 
                var e = new emp();
                     e.setSyncMode(); // I added here
                // If you set a callback handler for the proxy, the proxy's calls
                // are asynchronous.
                e.setCallbackHandler(populateEmployees);
                e.setErrorHandler(myErrorHandler);
            // The proxy getEmployees function represents the CFC 
            // getEmployees function.
                e.getEmployees();
            }

Thanks,

Richard

If anybody is still interested in this here is my javascript code that makes the ajax call:

function someFunction()

{

//make the ajax call to delete the item
var delRes = deleteTheItem(itemNum);

if (delRes == true)
{
//call the function to decrement the num of items value and update the totals or do whatever
}
else
{
//alert user delete not successfully
alert("You cannot delete this item ! This Item is being used for Receiving. You must first delete this item from receiving . ");
}

}//end function

//AJAX call to delete the item from the database
function deleteTheItem(iNo)
{

var prNum = document.frmPurchaseRequest.PRNumber.value;
var n = new myObj();
n.setSyncMode(); // this makes a synchronous call where nothing will happen until the call returns

//actual call to the the cfc, the result is either true or false -
var theRes = n.delItem(prNum,iNo); // the key is to capture the result in a variable
return theRes;
}

The above code works for me. It is important that you do not use the setCallBackHandler function cause it sets the synchronization mode to asychrononous.

hope this helps!
