Fixed datasets so an empty dataset isn't added if the create page is selected and the user navigates to a different page.
Fixed touched pages so the form needs to be changed and saved before it validates.
Fixed readonly display bugs:
- CSS selectors requiring !important
- Correct setting of readonly attributes in workflows.py
- Use hidden template for method_schema:name for readonly
- map_sequence.pt had a javascript bug where it was trying to access an element that is removed in the readonly template.
