closestack handler wait 1 second error

Any ideas why this:
Code: Select all
on closeStack
-- stop the timer
if sTimerState is "running" then
put "stopping" into sTimerState
end if
wait 1 seconds
pass closeStack
end closestack
Is now producing this error in LC 9.6 (on Linux and Windows haven't test on Mac yet):
stack "Count It Down": execution error at line 277 (wait: aborted), char 1
Line 277 is:
I originally made this app in 2018, I forget which version of LC I was using but, it wasn't causing this error.

Just made a fresh new stack with no controls, added your script and closed it without any error.
macOS 10.14.6, LC 9.6

I should clarify, this error is happening when closing the IDE with the stack open.

Aha, OK, just tested and still no error!?

Hi.
I will test also, but how are you closing the IDE? The handler you posted will not do so.

Maybe just QUIT?

Just by choosing "Quit" from the File menu.

Not sure what is pertinent here, but in a new stack with this in the card script:
Code: Select all
on closeStack
-- stop the timer
-- if sTimerState is "running" then
--put "stopping" into sTimerState
-- end if
--- wait 1 seconds
pass closeStack
end closestack
The stack window stays visible, even though the handler (visible because I was working from there) in the SE is deleted. Sending "closeStack" to the card by msg does the same thing. Of course, sending "close this stack" actually closes the stack.
The closeStack message is sent when the stack closes, and is not the trigger for that action just because it passes through that stack. But then why does the SE close the card script tab?

But that has nothing to do with your original issue, no?
Klaus, how did you do it? Same way?

Sure, since QUIT will close all stacks and they receive a "closestack" message.
BUT I raised the WAIT to 4 seconds and now I also see this error!

After reading up the dictionary, I am not sure if this is not desired behavior!?
Could you do this on closestackrequest?
That seems to be the right message for this.

That did the trick! Thank you!
Of course, this is making me think that any things you might want to do before allowing a stack to close are safer in a closeStackRequest handler than they are in a closeStack handler because it now seems apparent that if something in your closeStack handler takes too long, it can generate an error.

Note that closeStackRequest only fires if the user clicks the close box in the window title bar, it won't fire when quitting or closing the stack from a script.
Since you're quitting anyway, it doesn't seem necessary to reset the timer.
