If you publish a numbered list to a dashboard so that a User can insert items and then enter property values, it works fine as long as there is at least one item present. However, if you clear the numbered list then the option to insert an item is greyed out and I have found no way around that. Even if there is one or more items present the ability to insert a row is greyed out if you have selected the header row or the entire grid. That means you have to include a text box on the dashboard warning Users of this fact in order to avoid calls to support.
