Help! The code getting path information from

I could draw paths from the listener.log. But some paths are not shown in it.
Such as the curve path. What should I do?

I try to get code from “getter” plug-in. But it could not work, such as:
----------------------------------------------------------------
error = sPSActionControl->Play(&result, runtimeEventID, desc00002668,
plugInDialogSilent);
if (error) goto returnError;
----------------------------------------------------------------
It is error. Could you tell me what to do?

Could you describe it more particular?
I could get some codes from listener log file, such as the rectangle path and
ellipse path. But the Bezier curve path could not be shown in listener log file.
What should I do?
