hi miller, hi devs ...
having a look at the source code of route, i figured out, that it's not possible to use both numeric and symbolic selectors at a time ...
well, there is a short comment in the route help patch, but i'd propose to either fix this, or add a proper error message to the constructor ...
a proposal for this is attached and i'll commit it to devel, as soon as i'm online for more than 10 minutes ....
cheers ... tim
