Hi Edward and Daren,
"Listen to Actor" is invoked from the context menu on the canvas,
and the exception is also thrown when double-clicking on the Python
Actor to edit the script. These are probably run from the Swing
event thread.
Daren, thanks for verifying this problem occurs with Java 7 but not 6.
I updated Kepler a few months ago so that it would compile with Java 7.
However, when I ran it, I didn't exhaustively test all the
functionality. I'll create bug report so this error is not forgotten.

i resolved this issue temporarily by uninstalling java 7, thus
ensuring java 6 is being used. it all works fine now. hope that helps!

This sort of thing can happen for GUI code that invoked outside
the Swing event thread. How is this being invoked? If it's just
from the menu, then I presume it is in the Swing event thread...

Hi Daren,
I get the same behavior with Windows 7. The error is the same for
both "Listen to Actor" and editing a Python script:
java.lang.NullPointerException

Christopher, do you know what causes this?
Thanks,

I can use "Listen to Actor" for Kepler 2.3 on Mac OS X, but not under
Windows. When I select the option from the context menu, nothing
happens.
Also, when I try to edit a script for the Python actor, I get an error
message "Failed to open a dialog to edit the target (null)" - this
doesn't bother me ATM, but I guess I should mention it, as it could be
an additional symptom of a wrongly configured system.
I installed Kepler 2.3 on Windows with the installer provided on the
website. It seems "all" questions in the users list refer to compiling
your own version/environment. Is that the way to go?

Daren Thomas
