First of all, quite aside from the actual error, your use of
Future->needs_all on a list of a single future is totally redundant
there. You can replace that with simply

  $q->execute(...)->get;

Secondly, it's a little hard for me to reproduce this one locally
without seeing the table definition. Could you supply the CQL
definition used to create the table as well, so I can try it out for
myself?

Thanks for the reply, My perl is rusty so I wasn't sure if the problem was my fault or not, At the time I tried to dig into the driver source code without much luck, and concluded it was the driver after all.

I'll make a simple specific test case shortly. (I'm away overseas so it will have to wait until I get to a computer).

Thanks,
Jacob
