Re: [mapserver-users] msSearchDiskTree(): Errors

[Sean Gillies <sgillies@i3.com>]

Stephen,

I had the same symptoms when I first started using Python MapScript
on Win32.

A shapefile that was working for me with the Mapserv program was
not accessible through the mapObj.draw() method.

After pulling out half my hair I tried a different shape file and
had no problems.

The difference between my shapefiles is that the accessible file
was generated from ArcView and the inaccessible file was produced
by PCI Geomatics software.  I'm not certain why MapScript would
have higher standards for shapefiles than Mapserv (or ArcView).

Sorry that I don't have an answer for your problem, but maybe you
can use my experience.

cheers,
Sean
