Hi William Brumbelow,
The configuration you use is not correct. You are trying to map Telerik.Cms.Web.UI.NewsListCustom
, but there is not embedded template with this name. You need to map the hostType of the view you want to modify and then set the layoutTemplatePath to point to your customized template.
You can get a list of all hostTypes under [Sitefinity_3_6_1927_standard_ExternalTemplates]/App_Data/Configuration
