WMS Layer is not using my custom symbols

[Luca Manganelli]

Hi,

I use MapServer 5.0 as WMS server.
I have a Layer that uses a custom symbol. But I see it as a empty
polygon without dashed line as border. If I comment out the line with
SYMBOL "dash1", I see a continous line:

LAYER
  ...
  TYPE POLYGON
  ...
  CLASS
     NAME "test"
     MINSIZE 2
     MAXSIZE 5
     STYLE
        SIZE 3
        OUTLINECOLOR 0 0 0
        SYMBOL "dash1"            # <--- problem is here
     END
END

and in symbols.sym:

SYMBOL
	NAME "dash1"
	TYPE cartoline
	LINECAP round
	LINEJOIN round
	LINEJOINMAXSIZE 3
	STYLE 15 10 15 10 END
END

any idea?
