Integration Framework and multiple currencies

Hi Dw,

I have a big problem with the Integration Framework (Ax integration), which loads the cart from the ERP-system on "Dynamicweb.Notifications.eCommerce.Cart.Loaded" and this event happens in the first line marked with bold, but the Currency in the Context is first set in the second line marked with bold.

This result in this error: Attempt to aritmatic with two prices of different currency

As I see it, the right context should be loaded before the cart...

Friend Shared Sub LoadedPage(ByVal page As PageView)

Hi Anders,

I do see the problem, but unfortunately, we are not able to simply move the assignment to Context.Currency, as that is very likely to cause problems with some of the default implementations for calculating prices, carts, etc.

I seem to recall seeing this problem before, where the solution was to simply do the assignement to Context.Currency in the custom code, in the notification subscriber. Assuming you are using the AX integration as a replacement for the price calculations done in Dynamicweb, this should work as needed, without running into the problems we would face, if we tried to move it in our code.

If it doesn't work, please let me know, and I'll try to investigate further.

Regards, Jonas
