Grow dynamic text field vertically

[kidap]

I know you can expand the width of a text field horizontally with the .autosize property but i need to a text box's height to expand based on XML loaded text length. Is there a way to do this. I am loading a vertical list of components, each of which has a thumbnail photo and a brief description below it. The description is variable length and I want each component to be right under the next. If I give it the same amount of space for the description, the will sometimes be a gap and sometimes the text will be cut off. Any clues?

import mx.controls.List;


var my_list:List;

// create a new XML object
courses = new XML();
courses.ignoreWhite = true;
courses.load("fast.xml");

courses.onLoad = function(success) {
coursesNode =this.childNodes[0];

//scroll through xml list
for(i=0;i <coursesNode.childNodes.length;i++){
coursesNode =this.childNodes[0];
addList = coursesNode.childNodes[i].attributes.name;
my_list.addItem({label:addList, data:addList}); //add item in list

my_list.vScrollPolicy = "off"; //turn off vertical scroll
my_list.setSize(200); //(width , height) - setting the width only
my_list.rowHeight = 30; //spaces between each list item
my_list.rowCount = my_list.length; //height determine by list in xml
my_list.selectable = false; //items in list not selectable
}

}
