Double nested dynamic mc's

[Esseti]

Lets say I've created 10 dynamic MC's that have 10 dynamic MC's in each one. How can I address those nested MC's?

this.getChildAt("level1mc1").getChildAt("level2mc1"); - doesn't work
For some reason, Flash doesn't allow doubling this method.

You probably mean getChildByName, not getChildAt ;)

Anyway it doesn't work because getChildAt/getChildByName returns an DisplayObject which can't have any childs.
Casting it to the desired class should work:

((MovieClip)this.getChildAt("level1mc1")).getChildAt("level2mc1 ");

or just don't make it a single line:
var l1mc1:MovieClip = this.getChildAt("level1mc1");
var l2mc1:MovieClip = l1mc1.getChildAt("level2mc1 ");
