[MapServer-users] Issue with line colors in mapserver 8.4.0

[Rahkonen Jukka]

Hi,

What is the color that gets used? Is it some of the ones that you have defined in the CASE query?

Aihe: [MapServer-users] Issue with line colors in mapserver 8.4.0


Hello mapserver community,

Since we switched from mapserver version 7.6.4 to version 8.4.0, I have an issue with colors in line layers.
All dynamic color definitions (color is defined by a variable) are rendered with the same color. No matter if we use RGB- or HEX-Color values.
COLOR [VAR]

The values for the color  variable are defined by  an oracle SQL querry.


Example SQL:
DATA                    "geom FROM (SELECT id,status,zeitraum,   case   when Zeitraum in ( 2023) then '166 206 227'  when Zeitraum in ( 2024) then '31 120 180' when Zeitraum in ( 2025) then '227 26 28' when Zeitraum in ( 2026) the
n '255 127 0' when Zeitraum in ( 2027) then '253 191 111' when Zeitraum in ( 2028,2029,2030) then '251 154 153' when Zeitraum in ( 2031,2032,2033,2034,2035) then '51 160 44' when Zeitraum in ( 2036,2037,2038,2039,2040) then '178 223 138'
END  as color, geom,'Status: '||STATUS__LL||'</BR>Trassenlänge: '||trassenlaenge||'m' AS banner FROM my_oracle_table WHERE 1=1  ) USING UNIQUE ID SRID 25832 FILTER"


CLASS definition:

        END #CLASS


Is this a know issue or do you have any hint for me to solve it?
