IIF function

poosh

I'm currently using FastScript version witch comes with FastReport 4 Standard Edition v4.10.8. RAD Studio 2010.

Script sample (I'm using C++Script, but I have tested also PascalScript - same issue):

wrote:

{
String a = iif(true, "T", "F");
ShowMessage(a);
}

If this script is put inside a report - all OK, message shows "T".
But if executing inside the TfsScript object, message shows "0".
At this point it's not a big deal, cause IIF() function can simply be replaced by if..then..else statement.
But real problem starts with expression evaluation: TfsScript.Evaluate(), where IIF is the only way to define conditions.

Is it a bug, or I'm doing something wrong?

IIF function doesn't declared in FS. You must declare it in FS

No, it IS. If function isn't declared, "Undeclared identifier" error raises when trying to call it. I have also tried to redeclare this function using TfsScript.AddMethod(), but this doesn't work - script ignores my method handler and just calls native IIF function, which is buggy.
As a temporary workaround I've declared function with name IIF2, which does the same thing that IIF should. But it confuses end users.
