Hi,

We would like to create all custom product defintions programatically to ensure that when we release updates to the site we dont have to manually create all of the new definitions in the uCommerce production version. Looking at the API it looks like we should be able to do this using some code such as:

ProductDefinitionField productDefinitionField = new ProductDefinitionField();
                        productDefinitionField.DataType =
                            DataType.FirstOrDefault(def => def.DefinitionName.ToLower() == "boolean");
                        productDefinitionField.DisplayOnSite = false;
                        productDefinitionField.IsVariantProperty = false;
                        productDefinitionField.Name = "Test";

                        ProductDefinition productDefinition =
                            ProductDefinition.FirstOrDefault(node => node.Name == "Plastic Sheet");
                        if (productDefinition != null)
                        {
                            productDefinition.AddProductDefinitionField(productDefinitionField);
                            productDefinition.Save();
                        }

The issue is where/when this code can be executed. Being an umbraco 4.11 site, we implemented an ApplicationEventHandler and put this code in the OnApplicationStarted method - however we received the error:

System.Web.HttpException: Request is not available in this context

This was thrown on the productDefintion.Save() line.

Any pointers would be greatly appreciated.

Regards,

Al
