Hi!

Following this post: http://world.episerver.com/blogs/Linus-Ekstrom/Dates/2013/12/Customizing-the-look-and-behavior-in-the-UI-for-your-content-types/

I've created the following UIDescriptor, to let all my pages inheriting from BaseViewPage, show in AllPropertiesView:

[UIDescriptorRegistration]
    public class BaseViewPageUIDescriptor : UIDescriptor
    {
        public BaseViewPageUIDescriptor() : base("epi-iconObjectPage")
        {
            DefaultView = CmsViewNames.AllPropertiesView;
        }
    }

However, this results in a massive amount of javascript errors in the console, like:

If I uncomment the line DefaultView = CmsViewNames.AllPropertiesView, no javascript errors are thrown.

Am I missing something?

Best regards
