Couldn't find custom field22256 inside order backend

[ereallstaff]

I manage virtuemart product with custom field for CART ( eg. size ) on my modacalcio.it

Let's say I have S M L for a shirt , and some customers order size L

A customer purchase the last L , so I remove from product. The related custom field is dropped from DB table __virtuemart_product_customfield

When I go back in orders with the size L , the cart custom field is not shown , while a funny "Couldn't find customfield21456" statement is in.

This should be solved with a publish / unpublish custom field, or saving at the moment of order the custom field ordered inside order row?

Thanks

anyone else with the same problem?

Is it possible to modify custom field behaviour, with publish = 0 or 1 ? if yes how ?

Thanks

Looking inside the DB I have found 2 fields for each row inside #__virtuemart_product_customfields  , " custom_param ( PARAMS FOR PLUGINS )" and "published"   this may solve us a lot of problems.

Which cart_custom_fields uses them ?

Thanks
