C++ compilation failures when fusing operators that use the toJSON functions. #68

Closed ddebrunner closed 7 years ago

ddebrunner commented 8 years ago

This SPL will fail to compile:

use com.ibm.streamsx.json::toJSON;

public composite FuseJson {
   graph
     () as A = Custom() {
      logic state: rstring a = toJSON("a", 3) + toJSON("b", "4");
     }
     () as B = Custom() {
      logic state: rstring a = toJSON("a", true) + toJSON("b", "4");
     }
   config placement: partitionColocation("AB");
}

Functions should all be declared in-line:
