I am not sure how to resolve this object type not found problem. The message is like this: "The 'CustomModule.CustomerUDF' class belonging to the 'ecommerce.customer' object type was not found. This could be due to incomplete installation of the 'CMS.Ecommerce' module."
We've built a custome module but removed later. This custom module was tied to ecommerce.customer when I view it from System-->Object types. I don't know why all these custom module object types are still showing up here. How can I remove them? The module itself can't be found anymore. But all the object types related to the module are still there and I can't find a delete option.
