Well, dg.columns is an Array not an ArrayCollection so there is no need
to assign it as one. I'm actually surprised the assignment worked.
Anyway, you may have to make entirely new columns and copy properties
from the old one. That would look something like:
var c:Array = dg.columns.
var newCols:Array = new Array;
for (var i:int = 0; i < c.length; i++)
{
Var col:DataGridColumn = new DataGridColumn;
col.dataField = c[i].dataField.
col.width = c[i].width;
}
dg.columns = newCols;
If you can make a small example we can try to take a closer look.

Alex,
Sorry that I reply you so late.
You wrote me following code:
var c:Array = dg.columns;
fixupWidths(c);
dg.columns = c;
Was it a typo that you used array instead of a ArrayCollection.
I did in the following way, not working:
var cols:ArrayCollection = dg.columns;
cols.getItemAt(5).width = 60;
dg.columns = cols;
It was not working, telling me following errors:
A term is undefined and has no properties.

<http://www.adobe.com/2006/flex/mx/internal::res>
izeColumn()
at mx.controls.dataGridClasses::DataGridColumn/set width()
Please forgive me if I made a simple mistake. I am still learning.
Thanks,
Fudong
