[RESOLVED] Array string is textField or movieClip?

[somlemeg]

Converting AS2 to AS3 ,
In my project I have an array that refers to a set of movieClips and textFields.
I want to cycle trough the array and find out wether the string represents an movieClip or array.

var changeFocusItems:Array = new Array();
changeFocusItems.push("myMovieClip");
changeFocusItems.push("myTextFieldOnStage");

for each (var myItem:String in changeFocusItems) {
    if (myItem is TextField) {
        // do change textField property..
    } else if (myItem is MovieClip) {
        // change movieClip property
    }
} 

How do I recognise myItem string as a textField / movieClip?

Now I'v come one step further, but I have problem changing movie clip properties:

var myMovieClip:MovieClip = new MovieClip();
var changeFocusItems:Array = new Array();
var changeFocusItemsType:Dictionary = new Dictionary();

changeFocusItems.push("myMovieClip");
changeFocusItemsType["myMovieClip"]="m";
changeFocusItems.push("myTextFieldOnStage");
changeFocusItemsType["myTextFieldOnStage"]="t";
//changeFocusItems.push("mov1");
//changeFocusItemsType["mov1"]="m";

for each (var myItem:String in changeFocusItems) {
    trace(changeFocusItemsType[myItem]);
    if (changeFocusItemsType[myItem]=="t") {

        trace("is a text field");
        // do change textField property..
    } else if (changeFocusItemsType[myItem] == "m") {
        // change movieClip property
        trace("is a movie clip");
        var tmpMovieClip:MovieClip = new MovieClip();
        tmpMovieClip=MovieClip(getChildByName(myItem));
        tmpMovieClip.x=0;
    }
} 

the error occurs on tmpMovieClip.x=0;

solved.

var myMovieClip:MovieClip = new MovieClip();
addChild(myMovieClip);
var changeFocusItems:Array = new Array();
var changeFocusItemsType:Dictionary = new Dictionary();

changeFocusItems.push("myMovieClip");
changeFocusItemsType["myMovieClip"]="m";
changeFocusItems.push("myTextFieldOnStage");
changeFocusItemsType["myTextFieldOnStage"]="t";
changeFocusItems.push("mov1");
changeFocusItemsType["mov1"]="m";
//changeFocusItems.push("mov1");
//changeFocusItemsType["mov1"]="m";

for each (var myItem:String in changeFocusItems) {
    trace(myItem);
    if (changeFocusItemsType[myItem]=="t") {
        trace("is a text field");
        with (getChildByName(myItem)) {
            selectable=false;
        }
        // do change textField property..
    } else if (changeFocusItemsType[myItem] == "m") {
        // change movieClip property
        trace("is a movie clip");
        if (getChildByName(myItem)!=null) {
            with (getChildByName(myItem)) {
                x=100;
            }
        }
    }
}
