[mapserver-users] validation block

[Marc-André Trottier]

there is my layer's definition :

    LAYER
        VALIDATION
            ID_BASSIN '[[a-zA-Z0-9]{0,10},??]*'
            #ID_REG '[[a-zA-Z0-9]{0,10},??]*'
        END
        INCLUDE "../layers/bd/adn_station_max_v.map"
        CLASSGROUP "BASSIN"
        NAME "adn_station_bassin"
    END

    LAYER
        VALIDATION
            #ID_BASSIN '[[a-zA-Z0-9]{0,10},??]*'
            ID_REG '[[a-zA-Z0-9]{0,10},??]*'
        END
        INCLUDE "../layers/bd/adn_station_max_v.map"
        CLASSGROUP "REG_ADMIN"
        NAME "adn_station_reg_admin"
    END

with these commented lines a got this error :
msValidateParameter(): Regular expression error. Parameter pattern
validation failed.

without comment, i got no error.

CLASSGROUP 'BASSIN' contains many class but each class use only 'ID_BASSIN'
and
CLASSGROUP 'REG_ADMIN' contains many class but each class use only 'ID_REG'

is it the right thing to do ? or like i thought, the validation block can
contains only the variable used by the layer ?
