[Mapserver-users] Change layerobj's data property

[Eric Bridger]

I use this method with Mapserver/mapscript 3.6.6 with no problems.
But I don't rely on mapscript to use the SHAPEPATH, I always use the
full path for the layer->data member.  Try that.  You should be able to 
retrieve the SHAPEPATH from the map object $map->shapepath.
