I am using TeaCommerce 2 with the TeaCommerce Starter Kit (downloaded 24th May 2013) with Umbraco v6.0.5.
I am attempting to implement dynamic VAT rules for EU VAT numbers. This has been covered in a number of forum posts but only for TeaCommerce 1.x.
So far I have managed to adapt Rune's technique (http://rune.gronkjaer.dk/en-US/2011/04/12/tea-commerce-dynamic-vat/) along with Paul Blair's adjustment (http://our.umbraco.org/projects/website-utilities/tea-commerce/tea-commerce-support/29297-Euro-VAT-checking).
However, I have not been able to work out how to actually save the order property I have introduced (companyVATNo) despite having introduced it into the cart form and also the back-end order details page.
I did find this post (http://our.umbraco.org/projects/website-utilities/tea-commerce/tea-commerce-support/22378-Adding-custom-properties-to-an-order) which refers to modifying teacommerce_simple.js file but this does not appear to exist for TeaCommerce 2.
What is the correct method for saving new custom properties for an order?
Cheers,
Martin
