Using Record Getters and setters in object exception AddRecordJSON

Hi, (latest Mormot and Rio 10.3.2)

Whe we use record in property:

  TAllParkDeviceConfiguration = packed record
    DeviceID: Integer;
    IP: RawUTF8;
    PORT: Integer;
    MODE: Integer;      
    BAR_CLOSE: Integer; 
    TIM_ZAP_CLOSE: Integer;  
    TIMEOUT_PREHOD: Integer; 
    TIMEOUT_ISVALID: Integer; 
    TRIGER_LPR: Integer;  
    TIMEOUT_LPR: Integer; 
    PROVIDER: Integer;      
    GSM_SERVICE: RawUTF8;  
  end;

property MyRecord:TAllParkDeviceConfiguration read getMyRecord write setMyRecord;

it throws : Invalid TJSONSerializer.AddRecordJSON(41541b0e).

But if I use:

property MyRecord:TAllParkDeviceConfiguration  read fMyRecord write fMyRecord ;

We need this because we use Interfaces where get and set have to be defined.

Thank you,
Vojko

Re: Using Record Getters and setters in object exception AddRecordJSON

The property is from a class?
Record properties are not fully supported yet, since it is something not very stable in Delphi compilers, and not supported in FPC.
Any input is welcome.

As a workaround, you can define a variant published property, then return a TDocVariant content from the record for proper serialization.
Or a RawJSON published property - which may be even a bit more efficient.
Those types would support getters and setters.

I implemented published string property and use RecordSaveJSON and RecordLoadJSON.
Worka perfectly, Thank you
