Problem with multiple class styles when using attribute as color

[rafalmag]

When rendering a map with defined 2 styles and the second style is using attribute as color only the first style is rendered.

After rendering I always get wide, grey line. The one from second style is never rendered. But, when I change "[mycolor]" to "255 0 0" it is red, as it was supposed to be.

My temporary solution: When I delete first style (one with grey color) I get thin, red line (red is from column mycolor)

How to reproduce:

1. Define layer with data from PostGIS database.
2. In PostGIS table (next to the geom column) provide column called "mycolor" (type TEXT) with example data like: "255 0 0" or "#ff0000".
3. Use following styles:

   CLASS
          NAME    "line3"
          STYLE
                  SYMBOL "my_line"
                  COLOR 125 125 125 #gray
                  SIZE 8
                  ANTIALIAS TRUE
          END
          STYLE
                  SYMBOL "my_line"
                  COLOR [mycolor]
                  SIZE 6
                  ANTIALIAS TRUE
          END
   END
   

Where Symbol "my_line" is defined as:

SYMBOL
	NAME "my_line"
	TYPE cartoline
	LINECAP butt
	LINEJOIN round
	ANTIALIAS TRUE
END

Rafal also report that we do not appear to support colors of the form "#ff0000" in an attribute column, which should get fixed or at least documented.

Does this only occur in PostGIS? If you dump table as shape file and use that, is result different?

[rafalmag]

I am afraid that my case is far more complex than what it looks like. I use SQL function to generate that color request. I solved (actually omitted) this problem by moving "grey style" to bottom layer - it is not so fast, but my project can handle this.

Please try to reproduce problem on your own.

I have other work than trying to reproduce problems that may or may not exist. If you can show a case that works in shape file and doesn't work in PostGIS and attach a map file and table dump that produce the problem, I'll fix it. If you have a simple case that fails for both shape and PostGIS we should change the component.
