<br><font size=2 face="sans-serif">Does your virtual attribute depend on
other attributes of the same BOR object? That is, is it populated using
data from other sibling attributes? If these are not populated in
a timely manner then you can end up with a null value in your virtual attribute.
If this is the case ensure that any database-sourced attribute is
populated when you reference it in your virtual attribute.</font>

Obvious question: are there any recent updates prior to the failing step?<br>
Custom object/document/event? Does your attribute depend on DB data?<br>
