Great, that works! Thanks a lot!
And here is the next problem - how would I change the class expression
CLASS
EXPRESSION (1)
STYLE
COLOR 255 255 1
OUTLINECOLOR 32 32 32
END
END
"1" is for true, so all polygons are selected; I now want to change
the expression to (0) (= false), in order to deselect all polygons.
I tried:
map.layer[lakes].class[0].expression[0]='(0)'
and got:
loadClass(): Unknown identifier. Parsing error near ((0)):(line 1)
And for
map.layer[lakes].class[0]='expression+(0)'
I get
loadClass(): Unknown identifier. Parsing error near (expression (0)):
(line 1)
Moreover, for
map.layer[lakes].class[expression]='(0)'
msUpdateMapFromURL(): General error message. Class to be modified not
valid.
Anyone knows the correct syntax for changing this expression via the
URL?
Thanks for the great support,
Michael
