FixedColumns not working when data is loaded via array

WeaponX86

I have created two identical scripts, same doctype, css, javascript files, and data are used. When I apply DataTables to an existing table, the fixed column works, when I load a javascript array into aaData, it's broken.

Working example (Existing table):
http://dev.propertypreswizard.com/test_scripts/beta/right_column.html

Broken example (Data loaded via javascript array):
http://dev.propertypreswizard.com/test_scripts/beta/stretch2.html

In the second example, the right most column disappears, and I can see it (DTFC_RightWrapper) in Firebug but the position is off screen and the width is empty, it seems to be calculated incorrectly.

Any help would be appreciated.

Just for clarification, the broken example actually works if you define iRightWidth for the FixedColumn.
