Trying to get Products from Sitefinity but getting a "Object reference not set to an instance of an object" error.  The code looks like this;

public IList<Product> GetProducts()

var catalogManager = CatalogManager.GetManager();

List<Product> products = catalogManager.GetProducts().ToList();

return products;

Hi Tim,

Testing the sample seems works fine. Do you have any issues when open the products list in the backend (Ecommerce products)? Do you have the same issue when you get a list of other content types, e.g. News.

In addition, where this code is executed, in any custom control?  If so, can you provide this control here or open a support ticket?

Hi Svetoslav,

Sorry for delay, been on vacation.

Error does not happen when the object is referenced from a controller, it was only happening when I was unit testing the repository separately using Nunit. I am now calling the methods in the controller for testing and that appears to be working OK.

Thanks.
