public class LoyaltyPromo : RenderModel
{
public LoyaltyPromo(IPublishedContent content)
: base(content) // the error points here
{
}
//properties removed for brevity
}
I want to use this model inside UmbracoApiController. So i do this:
public class PromoServiceController : UmbracoApiController
{
public async Task<object> GetAll()
{
var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
IPublishedContent content = umbracoHelper.TypedContent(1050);
var list = new List<LoyaltyPromo>();
list.Add(new LoyaltyPromo(content));
}
}
Unfortunately it doesn't work, i get the NullReferenceException:
An error has occurred. Object reference not set to an instance of an
object. System.NullReferenceException at

Hi, Here is the screenshot where i'm getting the exception. Any help or hint is much appreciated.
Why are you using the rendermodel? The renderModel is normally used in the RenderMvcController
I would create my own model, or use the modelsBuilder class.
