I'm using the dissolve boundaries tool to merge adjoining polygons. I would like to calculate statistics for each polygon in the output based only upon the values in underlying polygons. However, whenever I specify a summary field the value in the output feature class is the value is the same for every record. It seems as though the attribute values are being calculated for a single multi-part geometry.(even though the 'create multi-part features' option is *not* checked and the resulting geometries are all single-part).
Am I doing something wrong? Is this a bug? Any ideas for a workaround?
