Hi Edson,
thank you for your reply.
I cannot use the solution $1 != null && $2 != null && $3 != null because the
number of parameters can be different in different rows.
I found a partial solution writing:

CONDITION    
myBean:Bean                                    
$param
My rule
...

and on the cell I write p1 == null, p2 == null and so on.

With this solution I don't need n columns anymore, but I must write "==
null" in the parameter rows. I would like to find a better solution. Have
you got any ideas?

Regards
Fabiano
