Fields SHAPE.AREA and SHAPE.LENGTH should be available in a feature service's attributes

Idea created by saschaaugsten on Aug 25, 2015
    If you add a feature service to a arcgis online web map you can display and configure all attributes of a specific layer in the pop up. But the fields shape.area and shape.length are not available. It would be good to display that fields so that a user can determine these values without using the measure tools.
