I had a quick play with the composition you linked to.
Looks like it's the 'folder images' patch causing the problem rather
than the javascript.
If you remove that patch it'll play again. If you put a folder
images patch in any other composition it won't play in Safari as
a .qtz file, BUT if you export as a .mov it will. Firefox doesn't
seem to mind either.
Weird.
Is there any documentation on this? Seems things are changing but as
Quartz Composer users and developers we really need to know what's
happening :-)
attempt to run this directly inside safari and you get an error
message
"the downloaded composition is unsafe and cannot be run inside
webkit..."
but if you download it and then run it in quartz composer it works
fine.
I assume this is because the composition contains javascript.
So Apple has already started to implement different sandboxing of
quartz composer
depending on where it is run....
I have no idea when this was introduced or what the criteria is for
this error message but I
am hopeful this principle can be extended to bring back the ability
to load compositions
inside compositions in some circumstances.
