mORMot2 TObjectList RegisterClassForJSON

As TObjectList is not a TPersistentClass it cannot be registered for JSON via Rtti.RegisterClass and TJSONSerializer.RegisterClassForJSON is not available anymore.
How can I register it as I use it extensively in mormot1 code migrated to mormot2

Thanks

Re: mORMot2 TObjectList RegisterClassForJSON

I'm not sure I understood you correctly, but this works without any registration:

var
  item: TItem;  // TItem = class(TObject)
  list: TObjectList;
begin
  list := TObjectList.Create;
  try
    list.Add(TItem.Create('value1'));
    list.Add(TItem.Create('value2'));
    ObjectToJsonFile(list, '_listData.json');
  finally
    list.Free;
  end;

With best regards
Thomas

Re: mORMot2 TObjectList RegisterClassForJSON

I have TJSONSerializer.RegisterClassForJSON(TObjectList) on Client app (XE4/mormot1) but had to comment that line out on server (D11/mormot2) as described in OP.
I pass the objectlist via Intertfaced based service method,e.g.

function CalList(var Lst:TObjectList):Boolean;
