Topic: Minor bug with polygon query

Just noticed this strange little bug. Not a huge problem, but worthy of note in case anyone else comes across it.

When using one of the polygon reports (actually a modified version of Records per polygon), we have been getting an error message which includes the following text:

exception class   : EAPIError
exception message : Error 87: The parameter is incorrect.

This arises in very particular circumstances when the polygon being queried has been created in MapInfo by making a ring-buffer around a point and then exporting to MID/MIF without first deleting the point. Thus the layer imported to Racorder includes both a polygon (ring) and a point. No error is triggered during import, it only happens when the report is run on the polygon.

Hope this helps someone one day
