Hi,

TMyRest = class(TRestServerFullMemory)
and register service
aServer.ServiceRegister(InvoiceService, [TypeInfo(IInvoiceService)],'1');

but in serivce methods self.server (TRestServer) is nil!

Re: Serive server is nil

How is TInvoiceService class defined?

Re: Serive server is nil

unit Service.Invoice ;

TInvoiceService = class(TInjectableObjectRest, IInvoiceService)
public
constructor Create; overload;
function GetInvoiceList(const DateFr,DateTo: string): RawJson;

function TInvoiceService.GetInvoiceList(const DateFr,DateTo: string): RawJson;
begin
--   self.server is nil here
end;

constructor TInvoiceService.Create;
begin
  inherited Create;
end;

I can't find anything wrong. Any suggestions?

Re: Serive server is nil

I guess because you created your own sicShared instance with your own TInvoiceService.Create without setting the property.
Auto-fill of the Server property is only if the framework make it.
If you make wrong initialization, it is... working wrong.

My guess is that you should call CreateWithResolverAndRest() as constructor, with the proper parameters, or just don't create your instance, but let the framework do it as sicShared, by providing a class and not an instance.

Can you try this:

aServer.ServiceRegister(TInvoiceService, [TypeInfo(IInvoiceService)], '1');     // <----   replacing InvoiceService with TInvoiceService

[dcc32 Error] View.Server.pas(109): E2250 There is no overloaded version of 'ServiceRegister' that can be called with these arguments

You could have searched a little bit:

aServer.ServiceRegister(TInvoiceService, sicShared, [TypeInfo(IInvoiceService)], '1');     // <----   replacing InvoiceService with TInvoiceService

Thank you so much. this one worked:
aServer.ServiceRegister(TInvoiceService, [TypeInfo(IInvoiceService)], sicShared, '1');
