Need help loading xml parameter into component

Question

I am using a third-party flash component (no source access)
that takes in a location of an xml file and manipulates it. The
problem is, I want that file's location to be dynamic and be loaded
from an argument to the end .swf that can then be forwarded to the
internal component. How can I load a component at runtime and set
it's xml_file parameter before/during construction of the object? I
have tried to drag it to the stage from components and change the
xml_file parameter in actionscript directly, but by the time this
change gets triggered the xml has already been read in and it
doesn't work.
This may be really simple, but I just can't figure it out. I
would appreciate anyone who could help. Thanks.

Answer 1

First, set the size of the component with the setSize method,
not "height" and "width". That may be the entire source of your
problem.
e.g.: this.componentInstanceName.setSize(175, 175);
Second, I am unsure all the parameters you specify in the
initialization object are valid {x:10, y:10, height:20, width:20,
font_color:'#333333', player:"vidPlayer", xml_file:"list.xml"}.
Only put in the initialization object parameters that are valid for
the component you are instantiating.
Third, make sure you are specifying the correct import
statements for your component at the top of your code. Since it is
a custom one, I can't help with knowing what to import. The code I
attached in my first post assumed import statements and the
components needed in the library, but here are the import
statements that I used:
import mx.controls.*;
import mx.containers.*;//for scrollPane
import mx.styles.CSSStyleDeclaration;
import mx.transitions.easing;
Fourth, don't forget the ignoreWhite method for importing XML
into Flash:
XML.prototype.ignoreWhite = true;// sets ignoreWhite
globally
