qgis - Getting polygon shapefile node coordinates and point order

I am trying to get the coordinates of each node of a polygon in QGIS. What I basically did is use the following tools:

Vector -> Geometry tools -> Extract nodes

Vector -> Geometry tools -> Export Geometry column

However only around the first 300 points had successfully obtained coordinate values in the new xcoord and ycoord fields. The other three thousand plus points had null values. What can I do to get the other points' coordinates? Also is there an easy way to get the point order of each node?
