logic behing formation of "Bill To" fields set?

[gkrellm]

Hello, dear enthusiasts, thanks for your hard work!

I'm trying to disable "Bill To" fields of VM 2, and simultaneously save "Ship To" fields and functionality.

But whereas there is a separate column named "Show in shipment form" in Shopper Field List, which is responsible for fields set for "Ship To" area, it's not obvious how to customize analogous field set for "Bill To" area.

And when I customize Shopper Field (see attach.) somehow that it has no fields in "Bill To" area, it still "asks" empty page on first checkout step in a loop without exit.

BTW, I use a modified ./administrator/components/com_virtuemart/views/userfields/tmpl/default.php, according to http://forum.virtuemart.net/index.php?topic=95669.msg314314#msg314314, to unlock some fields.

Code Select Expand

//$coreField = (in_array($row->name, $this->lists['coreFields']));

What is the logic behind the calculation of a required field set for a "Bill To" area?

Thanks for your attention.
