[Seaside] Coloring rows of a batched list accordingly an instvar value

[German Arduino]

Hi Guys:

I must show "data" that I read from an SQL Server db in a batchedlist.

Each row must be of a color determined by the value of one of the showed 
instvar (of the object that I build from the SQL database) to show in 
the batchedlist, but I can't figure out how to do this.

Any help will be appreciated.

Cheers.
