"Actions" menu is not displayed when selecting item from query results

Overview:
What to do if the "Actions" menu is missing.

Solution:

If a feature is selected and the "Actions" menu is not displayed, confirm if the geometry is being returned via a query from the services REST endpoint.  If no geometry is being returned, the "Actions" menu will not be displayed.  In one example, the fix was to unhide the "Shape" field, which revealed its geometry and displayed the menu.
