The problem

The problem is simply, that the wrong currency object is returned when using the CalculateOrderLineUnitPrice event in TeaComemrce version 2.3.2.

How to see the problem

I have implemented the method like this:

protected override Price CalculateOrderLineUnitPrice(OriginalUnitPrice originalUnitPrice, OrderLine orderLine, Currency currency, Order order)
{
    // This id is correct
    var curr = order.CurrencyId;

    // The Currency object seems to just return the first id possible.
}

I have set the currency like this:

TC.setCurrentCurrency({
    storeId: 1,
    currencyId: 3,
    successfn: function (data) {

        console.log(data);

    }
});

I have also tried setting the currency through Razor, but with the same result.

I really appreciate any help you can provide.

Update

After I've talked with Anders (from TeaSolutions) I can confirm this is an error in 2.3.2, and it has been fixed in the next version of TeaCommerce.

I made a hack until I have the possibility to update.
