How to access MC's textfield created in a custom class?

Question

I have a custom class which creates a new MC using a library MC. The  library MC contains a dynamic textfield called productName.
The custom class object gets created fine and is displaying on the  stage. It's also holding custom properties I set as well.
How do I control the dynamic textfield inside the MC, which is inside  the custom class object?
My Product.as:
package {
     import flash.display.MovieClip;
     public class Product extends MovieClip {
         public var prodName:String;
         public var prodCategory:String;
         public var prodQuality:String;
         public function Product():void {
             var productMC:MovieClip = new cellMC();
             addChild(productMC);
My .FLA first frame:
var myProd1:Product = new Product();
myProd1.prodCategory = "Heaters";
myProd1.x = 150;
myProd1.y = 140;
addChild(myProd1);
// THE FOLLOWING DOES NOT WORK
myProd1.productMC.productName.text = "ABC 123";
I figure something like this would work, but with lots of variations, still nothing works
I get errors telling me it can't find productMC.
UPDATE:
Using GetByChildName it seems I can access productMC. For example this works:
myProd1.getChildByName("productMC").visible = false;
But this does not work:
myProd1.getChildByName("productMC").getChildByName("productName").text = "dgdhdhdhrgh";
If I take the textfield out of the library MC, and create it in the class, then this works:
myProd1.getChildByName("productName").visible = false;
BUT this does not work:
myProd1.getChildByName("productName").text = "sdgsgdfsg";

Hi Otto,
If I well understood your situation, the solution  might be quite simple.
Since your Product class is a  MovieClip (and not a Sprite), you could solve your problem many ways  knowing that a MovieClip is a dynamic class.
But first,  the thing is that you created your productMC object on the fly inside  your Product class.
So either you correct it like this:
package {
     import  flash.display.MovieClip;
     public class  Product extends MovieClip {
         public var  prodName:String;
         public var prodCategory:String;
          public var prodQuality:String;
         public var productMC:MovieClip; // *****
         public function  Product():void {
             productMC = new  cellMC(); // *********
             addChild(productMC);
Or use this cheap trick (a MovieClip is a dynamic class):
package {
     import  flash.display.MovieClip;
     public class  Product extends MovieClip {
         public var  prodName:String;
         public var prodCategory:String;
          public var prodQuality:String;
         public function  Product():void {
             var productMC:MovieClip = new  cellMC();
             this.productMC = productMC; // **************
             addChild(productMC);
Although it is possible that, for this one, you need to reforce the dynamic property:
package {
     import  flash.display.MovieClip;
     dynamic public class  Product extends MovieClip {
I am not sure, but anyway, you will see for yourself.
Plus, you try to change text to a MovieClip object? Either there is already a TextField in you cellMC object and you are not targeting it, or productMC should be instanciated as a TextField and not a MovieClip. I think you know the answer to that.
