Hi guys,
For some reason solution is ignoring Validation groups setted up in MC>Ecommerce> Orders> Validation groups
After theese rules where created, I went to cart module, and made sure they are selected and have error messages. http://screencast.com/t/L2cUlBBt7yvi
But as a result, solution just ignores them.
Any idea, hints, suggestions what can be wrong?
