HTML legend not created in mapserver 4.6.1

[Vito Meuli]

Hi Ken,

this is an interesting piece of information added to my understanding of the 
problem.

I have no cartoline symbol, but I have lots of layers that draws outlines of 
polygons!

I've tryed leaving out ALL my ANTIALIAS TRUE from my mapfile, but the problem 
remains.

I can let the legend come back only removing layers one after the other. At a 
certain point, the legend comes back.
But if I put in again the last layer removed, I can let the legend come back 
removing a class after the other.
The classes are all similar to this one:

        CLASS
                NAME "Edilizia esistente"
                EXPRESSION "B"
                STYLE
                        #symbol 0
                        COLOR 224 166 166
                        OUTLINECOLOR  0 0 0
                END
        END  # CLASS

The layer that actually triggers the problem on (having removed a lot of other 
ones) is the following:

LAYER # layer delle subaree del PRG - urb primaria
        NAME "urb_prg_subaree"

        METADATA
                cliccabile "SI"
                visibilita "da 1:25.000"
        END

        DATA "the_geom from prg_subcomp"
        GROUP "Piano di Fabbricazione"
        TYPE POLYGON
        STATUS DEFAULT
        CONNECTIONTYPE postgis
        CONNECTION "user=sanpancrazio password=sanpancrazi0 
dbname=sanpancrazio host=localhost port=5432"

        PROJECTION
                "proj=tmerc"
                "lon_0=15"                      # longitudine dell"origine
                "x_0=2520000"                   # falsa x
                "k=0.9996"                      # fattore di riduzione di 
scala
                "ellps=intl"                    # espressione dell"ellissoide 
terrestre
        END

        CLASSITEM sottozona

        CLASS
                NAME "Strada di P.R.G."
                EXPRESSION "_S"
                STYLE
                        #symbol 0
                        COLOR 240 240 240
                        OUTLINECOLOR  0 0 0
                END
        END  # CLASS

        CLASS
                NAME "Centro Storico"
                EXPRESSION "A1"
                STYLE
                        #symbol 0
                        COLOR 200 200 200
                        OUTLINECOLOR  0 0 0
                END
        END  # CLASS

        CLASS
                NAME "Edilizia esistente"
                EXPRESSION "B"
                STYLE
                        #symbol 0
                        COLOR 224 166 166
                        OUTLINECOLOR  0 0 0
                END
        END  # CLASS
END


However my colleague says the problem seems to come out randomly when he adds 
layers to a mapfile.

I really can't understand what triggers the problem on, so I can only try to 
come back to Mapserver 4.4.2 and hope...

Should I add this email to Bugzilla? How does it work?

Thanks a lot for the help.
Cheers,
Vito
