[mapserver-users] PHP MapScript: shape->classindex is always 0

[Josh Hevenor]

I think I came across the same thing, or something related, when I was
trying to generate KML using mapserver templates.   I know I ended up
recreating the class expression in my output instead of using the
[shpclass] variable.  Let me know if a bug is filed and I'll work up an
example to submit.  (mapserver 5.2)
