[Boost-users] Signals, Format and Bind

I have two signals:
signal<void(int)> source;
signal<void(string)> target;

What want is for every call:
source(12345);
to have a call:
target("the value is 12345");

I am trying to achieve this with format and bind, but without much luck. 
  What I came up with is the following:
source.connect(bind(ref(target),
     bind(&format::str,
         bind(&format::operator%,
             format("the value is %1"), _1)));

Unfortunately the code above treats the parameter to source as if it was 
empty, i.e. I get calls
target("the value is ");

What am I doing wrong and how can this be done correctly?
