Try something like the following (I'm using result here instead of
lastResult, but see what works for you:
var acResults : ArrayCollection;
if (myListRequest.lastResult.records.record is ArrayCollection)
{
acResults = myListRequest.lastResult.records.record;
}
else
{
acResults = new ArrayCollection();
acResults.addItem(myListRequest.lastResult.records.record);
}
Alert.show(acResults.length.toString());

Thanks Steve for explaining exactly the root cause.
What method would you recommend to test if the
result is an array or an object ?
