Hi people,
I am having the strangest problem. When setting a symbolsetfile to a
mapObj with mapscript in python, and in the same script creating a
classObj with an expression, I get an error: mapscript.MapServerError:
loadSymbolSet(): Unknown identifier. Parsing error
I limited the error down to a small testscrip which is below. If I
remove eiter one of the last two lines in the script, the error
disappears. In the original script also layers and stuff (connection
through ogr to postgres/postgis) are added, but that makes no
difference. I also included my symbols file (see below). I added a BOF
and EOF below to show the beginning and ends of the files, of course
they are not in the actual files. The full traceback of the python error
can be seen below as well. I am running Python 2.4.4 on Debian Sarge
with a self compiled version of mapserver 4.10.0, gdal 1.3.2 and proj 4.5.0.
I have no idea what the problem is. I hope anybody can help.
Thanks,
Dolf.
