Fast DDS 2.3.0 could not subscribing properly.

[ilikecola]

Expected Behavior

RTPS works properly.

Current Behavior

ReturnCode_t is RETCODE_NO_DATA.

Steps to Reproduce

datawriter code (excerpt)

datareader code (excerpt)

powershell running

System information

• Fast-RTPS version: 2.3.0
• OS: windows10
• Network interfaces: lo (127.0.0.1)

The IDL strcuture is:

struct IdentifiedObject {
                @key                TC57CIM::JiangSu::CommonModule::uuidType mRID;
                TC57CIM::JiangSu::CommonModule::String64 name;
            };

struct BreakerStatusProfile : TC57CIM::JiangSu::CommonModule::StatusMessageInfo {
                TC57CIM::JiangSu::BreakerModule::BreakerStatus  breakerStatus; 
                TC57CIM::JiangSu::CommonModule::IEC61850IED  iEC61850IED; 
            };

struct IEC61850IED : TC57CIM::JiangSu::CommonModule::IED {
                sequence<TC57CIM::JiangSu::CommonModule::LogicalDevice,5>  logicalDevice;
            };
struct LogicalDevice : TC57CIM::JiangSu::CommonModule::IdentifiedObject {
                sequence<TC57CIM::JiangSu::CommonModule::DDSDomainparticipant,2>  dDSDomainparticipant; 
            };

@ilikecola In order to analyze this properly, we will need the full IDL, including all modules

[ilikecola]

Here is my full IDL:

module TC57CIM {
    module JiangSu {
        module CommonModule {
            struct IdentifiedObject;
            struct MessageInfo;
            struct StatusMessageInfo;
            struct IED;
            struct IEC61850IED;
            struct LogicalDevice;
            struct DDSDomainparticipant;
            typedef string String64;
            typedef string uuidType;
        };
        module BreakerModule {
            struct BreakerStatusProfile;
        }; /* module BreakerModule */
    };
};

module TC57CIM {
    module JiangSu {
        module CommonModule {
            struct IdentifiedObject {
                @key TC57CIM::JiangSu::CommonModule::uuidType mRID;
                TC57CIM::JiangSu::CommonModule::String64 name;
                @optional TC57CIM::JiangSu::CommonModule::String64 description;
                @optional TC57CIM::JiangSu::CommonModule::String64 aliasName;
            };
            struct MessageInfo : TC57CIM::JiangSu::CommonModule::IdentifiedObject {
                octet __dummy_prevent_empty_class_MessageInfo;
            };
            struct StatusMessageInfo : TC57CIM::JiangSu::CommonModule::MessageInfo {
                octet __dummy_prevent_empty_class_StatusMessageInfo;
            };
            struct IED : TC57CIM::JiangSu::CommonModule::MeasurementValueSourceEx {
                octet __dummy_prevent_empty_class_IED;
            };
            struct IEC61850IED : TC57CIM::JiangSu::CommonModule::IED {
                sequence<TC57CIM::JiangSu::CommonModule::LogicalDevice,5>  logicalDevice;
            };
            struct DDSDomainparticipant : TC57CIM::JiangSu::CommonModule::IdentifiedObject {
                @optional TC57CIM::JiangSu::CommonModule::String64 partition;
            };
            struct LogicalDevice : TC57CIM::JiangSu::CommonModule::IdentifiedObject {
                TC57CIM::JiangSu::CommonModule::String64 inst;
                sequence<TC57CIM::JiangSu::CommonModule::DDSDomainparticipant,2>  dDSDomainparticipant; 
            };
        };
        module BreakerModule {
            struct BreakerStatusProfile : TC57CIM::JiangSu::CommonModule::StatusMessageInfo {
                TC57CIM::JiangSu::CommonModule::IEC61850IED  iEC61850IED; 
            };
        };
    };
};

@ilikecola I think this may be related with eProsima/Fast-DDS-Gen#60, which was solved by eProsima/Fast-DDS-Gen#61

Could you try changing @key with @Key ?

[ilikecola]

Thank you!
The problem is solved perfectly!

Hi @MiguelCompany I recently tried to create dynamic data using IDL file with -typeobject option. But when I use @Key annotation -typeobject causes segmentation fault when I run GetCompleteXXXObject(). Example idl:

module a
{
	module b
	{
		typedef long long t1;
		struct c
		{
			@Key string aa;
			@Key string bb;
			long cc;
			a::b::t1 dd;
		};
	};
};

Also if I use lower case @key, the subscriber still receives RETCODE_NO_DATA when a publisher sends a DynamicData created by DynamicTypeBuilderFactory.
