I'm using Commerce Postal Code Filter to blacklist some delivery postcodes.
When a delivery matches the blacklist validation fails and form_set_error is applied.
The problem here is that this means the Customer Order fields and Customer Profile Shipping fields are not saved.
I know this is normal, because failed validation in other tests could mean illegal entries.
For the postcode filter however, I'd still like to save data on failed validation. This will allow the client to see the user's input delivery address and telephone in order to make a call.
Any ideas how to go about this?
Ideas - Set to validate, but change order status - could this make it serve first checkout page?
