BeforeSubmit Script not working for Web Orders

Hi,

I have a very simple BeforeSubmit script that I am trying to run on Sales Orders created through the webstore that sets the Department field to a default value:

function setOnlineSO(type)
{
var currentrecord = nlapiGetNewRecord();
currentrecord.setFieldValue('department',1);
}


I have created a user event script to trigger on BeforeSubmit and I have deployed it using the following criteria:
- applies to sales orders
- deployed = yes
- status = testing
- event type = create


I have opened up the script to run on all sales orders (not just web orders) for testing.  The script behaves as expected for sales orders created through the UI but it is not working for sales orders created online.
