If you want to loop over the keys (the names of the components), you
need a for-in loop:
for (var key:String in dynamicallyCreatedComponents)
A for-each-in loop loops over the values (the references to the
componetns).
There is no such thing as a for-each-as loop as you've written below.

Subject: [flexcoders] Re: getChildByName using it to get the value of a
textbox
Can i loop through the items in that object
example
for each(var items:String as dynamicallyCreatedComponents){
var t:TextInput = dynamicallyCreatedComponents[items] as TextInput;
Alert.show(t.text); //THROWS ERROR
}
I was hoping to set the array key dynamically and loop through it later?
can this be done Gordan
