Importing a CSV file with a single point fails with a error message:
Failed to publish csv:
24305: The polygon input is not valid because the ring does not have enough distinct points. Each ring of a polygon must contain at least three distinct points.
The silverlight plugin will crash too. My file is simply a header row and a single row of attributes. I want to import a simple point into a map to use as a reference and then add different map documents into a mashup. Each reference layer has will have unique information in the pop-ups rather than a common set of attributes.
