Hi all,
Using etoys in class (11th grade in Germany) on Linux (ubuntu gutsy)
several pupils had the problem not to be able to save their porject due to
an 'error: duplicate selector'.
This error shows up as well, when they are dragging a 'players'-tool from
the supplies flap into the world.
Some debug-logs for these two situations are attached.
I'm not sure, what they did wrong. Since several pupils had this problem
already, this might be a rather common mistake. Maybe they had a variable
and a script with the same name, or they deleted a script and created
another one having the same name. Unfortunately I don't know what they
did, and they weren't able to tell me what they had done that might cause
the problem.
Any ideas?
Markus
