symbols from 4.4.1 to 4.6.1

[toni hernández]

hi,
After serveral hours of trying..
I can state now that:
I am crazier
and
If you want the symbols of you mapserver (4.6.1 ) application  to be 
shown you HAVE TO include the attribute color in the class definition, 
even when the symbol is comming from a file.
Does it make any sense? I have a 4.4.1 version running and the color 
attribute is not necessary.

Anyone can tell me why?
