    }

Hi,

The code is working, but EPi CMS still render "OnPageEditView" before switching to "AllPropertiesView". Switching hangs sometime. Is this a bug? 

Thanks,

Sounds like a bug...

That code should be working...

It works the opposite in my case. It always shows AllPropertiesView even when i changes to OnPageEditView. Can't say its a bug, because it works in alloy site.

 [UIDescriptorRegistration]
    public class SitePageUiDescriptor : UIDescriptor<SitePageData>
    {
        public SitePageUiDescriptor() : base(ContentTypeCssClassNames.Page)
        {
            DefaultView = CmsViewNames.OnPageEditView;
        }
    }

By going through https://world.episerver.com/blogs/grzegorz-wiechec/dates/2017/9/sticky-view-mode/ i found that, its new feature in Episerver 10.11.0 onwards which shows previously selected view, i solved it by adding 

EnableStickyView = false;
