Hello Krati,

as stated in the below exerpt from the QF-Test manual, the option
OPT_PLAY_WRONG_THREAD_ERROR_LEVEL requires an 'SUT script' (not a 'Server
script').

To check an option value, use rc.getOption().


Best regards,
   Robert

Hi,

I'm trying to change wrong thread events error level to warning with
Jython Server script from Event Handling options, but not succeeding.
This is how I tried (the whole script):

val = Options.VAL_PLAY_THREAD_LEVEL_WARNING
rc.setOption(Options. OPT_PLAY_WRONG_THREAD_ERROR_LEVEL, val)

Should there be something else also because this is not working? I
checked the options from your Manual from this section:

How to handle events coming from the wrong thread (System)
      SUT script name: OPT_PLAY_WRONG_THREAD_ERROR_LEVEL
      Possible Values: VAL_PLAY_THREAD_LEVEL_WARNING,
VAL_PLAY_THREAD_LEVEL_ERROR, VAL_PLAY_THREAD_LEVEL_EXCEPTION

      It is a rather common mistake in Swing based Java applications to
access GUI components from the wrong thread. Since Swing is not
thread-safe, such calls may only be made from the AWT event dispatch
thread. Otherwise the potential consequences are race conditions, leading
to very subtle and hard-to-debug errors, or deadlocks, freezing the
application and making it unusable. Background information about this
topic is available from
http://download.oracle.com/javase/tutorial/uiswing/concurrency/index.html
, specifically the sections on "Initial Threads" and "The Event Dispatch
Thread".       When QF-Test registers an event on a thread other than the
AWT event dispatch thread it issues an error message including a stack
trace which can be useful in fixing the problem. This set of options
defines the severity of the message, whether to perform strict checking
and a maximum for the number of messages to log.       The possible
choices for the option "Error level" are "Error" and "Warning". We
strongly suggest that you keep the default setting of "Error" and make
sure that such problems are fixed sooner rather than later because they
represent a serious risk.


Another question is that how can I check the current value of 'Options.
OPT_PLAY_WRONG_THREAD_ERROR_LEVEL'? I have version 3.5.0 from QFtest.

Thanks and Br,
Katri
