Hi Systeembeheer UNIT4,
This issue is fixed internally and will be shipped with the next SDK release. By the way, your first fix seems correct, but you will have to restart the server before trying it again.
Basically, you have to open ProductsResources.cs, then add
/// Title of the Products
Then kill the server and launch it again.
This should solve the issue.
