Live integration - Error in FindPrice()

on a site with liveintegration to NAV we are getting a lot of errors like this:

Error: Unknown error during FindPrice(). Exception: Type 'Dynamicweb.eCommerce.Products.ProductVatGroupCollection' in Assembly 'Dynamicweb, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

We are using the sample live integration supplied by DW, where we have made the nessesary changes.

The Error is beeing looged from PrepareProductInfoProvider.cs / FindPrice(.......).

There has been made no changes to that method.

Does anybody have some good pointers to where i should look to solve the bug, or is it a bug in DW

Hi Kenneth

Can we see the full stack and your entire integration project?

Also information on which version you are running on.

Hi Kenneth

The problem on this is this piece of code in our sample code:

if (Product.VariantID == VariantID || (string.IsNullOrEmpty(VariantID) && string.IsNullOrEmpty(Product.VariantID))) {

requestProduct = Product;

}

else {

requestProduct = Product.Clone();

requestProduct.VariantID = VariantID;

}

When the price provider is used for products with variants, the product instance is cloned - and that it should not. The integration framework does not support variants out of the box, since NAV etc. does not have a standard solution for variants.

The solution is to remove the conditional and not clone the product instance, but simply use the same instance wether it is a variant or not.

We have changed this in our sample code and will release an updated version.

Solutions with no variants is not impacted.
