Business Rules Function

Data Abstract

IDE: Delphi XE6
Version 9.2.103.1311 Server Edition

Hi,

I need to call a function in a Business Rules I found this code but is not working I got this error:

procedure RegAudit(args: array of variant);

procedure TSRG_DataService.RegAudit(args: array of variant);
begin
//
end;

procedure TSRG_DataService.DataAbstractServiceActivate(const aClientID: TGUID;
aSession: TROSession; const aMessage: IROMessage);
begin
EcmaScriptProvider.Engine.Variables.SetVariable(‘RegAudit’, RegAudit);
end;

Error:
[dcc32 Error] SRG_DataService_Impl.pas(75): E2250 There is no overloaded version of ‘SetVariable’ that can be called with these arguments

what is wrong ?

Regards!

you have declared RegAudit incorrectly.

TDAEcmaFunction = function (args: array of variant): variant of object;
procedure SetVariable(aName: string; aFunc: TDAEcmaFunction);overload;

so your RegAudit should be

procedure TSRG_DataService.RegAudit(args: array of variant): variant;

Note. in some versions of Delphi, direct assignment may not work, so you need to use code like

procedure TSRG_DataService.DataAbstractServiceActivate(const aClientID: TGUID;
aSession: TROSession; const aMessage: IROMessage);
var
  f: TDAEcmaFunction;
begin
  f := RegAudit;
  EcmaScriptProvider.Engine.Variables.SetVariable(‘RegAudit’, f);
end;
