[mapserver-users] Shapefile,itemnquery and HTML image map generation problem

Mon Dec 7 16:56:54 PST 2009

Do the ones not selected fall at the end of your qstring? I'm wondering if something is getting truncated. I'd think
you'd get a parsing error in that case, but perhaps not. Can you label the polygons with the value for MLRARSYM?
