Don't know if this is exactly what you are asking for, but this is
another way to determine the number of results:
private function handleNewProductsResult(evt:ResultEvent):void {
if (evt.result.products == null) {
// there are no results
newProductCount = 0;
}
else if (evt.result.products.product[0] == null) {
// not an array, so there is only one result
// and the result is evt.result.products.product
newProductCount = 1;
}
else {
// is an array with more than 1 result
newProductCount = evt.result.products.product.length;
}
//...
}
