Question

I have a ScrollPane component to stage and I give it as source a new MovieClip instance. How can I access the movieclip inside scrollpane?

This is what I have so far but it returns null:

var regForm = new RegistrationForm();
regForm.name = "rForm";
regFormSP.source = regForm;
var form = Object(regFormSP.content).getChildByName("rForm");
trace(form) // returns null

UPDATE

If I list objects I get

_level0.regFormSP.instance20.rForm

There is an object “instance20” as a parent to rForm…Why is that?

Answer 1

instance 20 is probably an unnamed container inside the scroll pane that Flash masks and scrolls. According to the docs, ScrollPane.content is a reference to the display object you assign using ScrollPane.source. Given that, regFormSP.content should be your form, and not child thereof.
