Calculated column not updating when document property changes

[Chad Holland]

I have setup some cascading document properties. Due to number of values though, I am using a text box for the user to input their username instead of a drop-down; however, I did try with a drop-down too just to test. This text field changes a document property, which feeds to a calculated column. The problem is, when the document property changes, the calculated column is not getting updated.

Note, I put in the following script on property change:DataTable = Document.Data.Tables["sap_users"].Refresh()

This is very slow to update and not fluid at all. I have used this cascading method before, and never had this problem.
