The dynamic send port in your orchestration must have its address
specified somewhere within the orchestration. Maybe you thought you put
it in there, like I did, but double check, because that is what is
causing this error. Here is how you specify the address in an
expression editor:
DynamicPortName(Microsoft.XLANGs.BaseTypes.Address) = [your address
string];
Hope that helps somebody out there...
