SetFMEDirective method of Server .NET API doestn't work

Hi,

 

 

IFMETransformationRequest.SetFMEDirective(s) method of .NET API seems doesn't work.

 

And I try Java API, there is no this problem.

 

Tested on FME Server 2013 Build 13264 x86.

 

 

==========================

 

request.SetFMEDirective("x", "xx");

 

Debug.WriteLine(request.GetFMEDirective("x");  // here return ""

 

request.SetPublishedParameter("y","yy");

 

Debug.WriteLine(request.GetPublishedParameter("y")); // same object's GetPublishedParameter method return right value.
