For the record - I figured out my problem, which was a bit of confusion about what was an actor and how to access closure members. The "ref" passed in is a phoenix::actor, NOT the closure member itself, so to access the closure member, the operator()() of the actor needs to be invoked - substituting into the do_appender::act below:
String& value(ref()); value += val;
Of course, if act is called with something other than an actor, THIS will break, but I'm thinking it should ONLY be fed actors... And for my purposes, only an actor that returns a std::string&.
That's good to hear. To be honest, I had a difficult time trying to read the code in your post. In the future, it's always a good idea to attach a minimal cpp file that we can try without much fuss. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
