---------------------------------------------------------------
Simplest fix is to just clear the pn_data_t before new insertion:
{code}
diff -c message.cpp.cj0 message.cpp
*** 143,148 ****
--- 143,149 ----
void message::correlation_id(const message_id& id) {
codec::encoder e(make_wrapper(pn_message_correlation_id(pn_msg())));
+ e.clear();
e << id;
}
{code}
But perhaps new encoders should clear by default as the more intuative use (and
have a separate constructor for the "and save my current position" case).
