I have a similar problem and I've given up on it. But that doesn't mean
that you shouldn't keep trying and tell me if you found a solution ;-)

No, the request looks like this:
listname=value1&listname=value3
This is how multiple values are encoded. To read multiple values from a
request, you can do rundata.getParameters().getStrings("listname"). This
returns a String array of all values.
rundata.getParameters.getString("listname") only returns the first value
of a multivalue parameter. If I understand correctly, this is how
Jetspeed reads the parameters in CustomizeAction.doUpdate() (where I
think the customize requests are handled), at least in b4, I don't know
about the newest CVS version.
So I think that at the moment, you cannot use dynamic multiple values
with parameter styles :-(
