When you install a new Orchard instance using the clayless branch and create a Query with a ContentTypes filter, you will get an InvalidOperationException: " Invalid base type for shape: Orchard.Forms.Shapes.PropertiesAreItems"
See attachment for a more colorful representation of the error.
Steps to reproduce:
- Clone the repo.
- Update to the clayless branch
- Build and launch the site
- Create a new Query
- Add a new Content Type filter. You will now see the error.
