Flex DataGrid last empty column dynamic width

Question

Goal: have a blank right-most column in a DataGrid that takes
up the slack in case the other columns do not total 100% of the
overall grid width.
This is what I have, which seems to work:
<mx:DataGridColumn editable="false" sortable="false"
minWidth="0"/>
I am wondering if there is a best-practice way of specifying
such a last column that is better than the above tag.
Flex SDK 3.2
Thank you,

It worked!!!!!!! Thank you!! What you mentioned was indeed the problem!
Here is the custom item renderer's set data function
Before
Now
override public function set data(value : Object):void{
                  super.data = text;
                  this.txt.text = (value as Slide).text ; //txt is the Label control
override public function set data(value : Object):void{
                  super.data = value;
                  this.txt.text = (value as Slide).text ; //txt is the Label control
oh man, this is such a stupid mistake. I think I was confused with having three text properties - one inherited from MXDataGridItemRenderer, one in my txt Label control and one on my slide.
I had no idea that sending the value up to the super class was so important. None of the docs I read seemed to give much importance to this statement.
thanks so much and sorry for taking up so much of your time. I guess it is uncessary to post any more code.
