reverse set ComboBox as3

You can use selectedIndex to change a comboBox, but the selectedIndex is usualy independent from the data or the label properties of the Object. Apparently there is no way of doing a reverse look up to select the item, you have to searh through and find it yourself (if you know a better way, let me know!).

function reverseSetComboBox(target:String, targetComboBox:ComboBox, targetDataProvider:Array):void {
        //loop over the items in the dataProvider
        for (var i:uint = 0; i<targetComboBox.length; i++) {
                //compare desired value to current value
                if (target==targetDataProvider[i].label) {
                        //set the seletedIndex of the combo box
                        targetComboBox.selectedIndex = i;
