Hi Team, While doing typecasting from boost::any to DecodeErrorPayload_t, its throwing bad_any_cast .. class RegisterIONotification { public: enum NotifyType { TypeUnknown, TypeRegTx, TypeRegRx, TypeDecodeError }; NotifyType Type; boost::any Payload; typedef boost::tuple<std::string, BinaryBuffer_t> DecodeErrorPayload_t; RegisterIONotification(NotifyType type;,boost::any payload) { Type(type); Payload(payload); } }; I have called RegisterIONotification from other class function. void RegisterIOThreaded::OnDecodeError( const std::string& error, BinaryBuffer_t data ) { RegisterIONotification notify(RegisterIONotification::TypeDecodeError ,make_tuple(error, data)); ..... .... ... } While testing, I am getting bad_any_cast exception. TEST_F(...,...) { RegisterIONotification notify = sink.GetDataById(ID::NOTIFY_COMMS_STATUS, 0).GetValue<RegisterIONotification>(); ASSERT_EQ(RegisterIONotification::TypeDecodeError, notify.Type); //passed RegisterIONotification::DecodeErrorPayload_t payload; ASSERT_NO_THROW(payload = boost::any_cast<RegisterIONotification::DecodeErrorPayload_t>(notify.Payload));// Here its got failed...Please help me to fix this. } Regards, Rajesh D Please be advised that this email may contain confidential information.
