Wrong method signature generated when using nullable enum as parameter type

[querbyte]

Example:

[CreateAngular2TsProxy(ReturnType = typeof(List<Foo>))]
public ActionResult Get(int id, MyEnum enumValue)
{
	//...
}

generates

public get(id: number, enumValue: MyEnum) : Observable<Foo[]> { 
	return this.http.post('api/Foo/Get'+ '?id='+id,enumValue) as Observable<Foo[]>;
}

The generated method does not work as expected and handle the enum value as a complex type and send the value in the body of the post request. So on the server side you never receive a valid value for the enum, it is always null.
