The issue occurring with loading the designer for this MVC based widget is that the designer can`t be found.
When adding designer there are 2 requirements, I have attached a widget with a functional designer refer to CorticonResponseWidget+Designer.zip.
1. The designer must be linked to the controller via a decoration as you have mentioned
, Title =
, SectionName =
2. The designer must inherit from ControlDesignerBase
CorticonResponseDesigner : ControlDesignerBase
Refer to the attached sample widget + designer for reference, compare with the designer and controller at your end to spot the cause of the problem.
