In my main stack there is a preOpenCard handler. Now, every time
one of my many subStacks is opened, the preOpenCard handler of
the main stack tries to run, and since it involves objects unique
to that stack, and the handler is trying to perform itself in the
subStack, I get an error, something like "oject doesn't exist, "
The script of the mainstack is accessible from all substacks,
acting as a common repository of handlers, so what you're seeing
is normal.
Three ways to have your mainstack-specific scripts only triggered
in the mainstack:
- If the mainstack has only one card, consider putting the
mainstack-specific scripts at the card-level.
- If the mainstack has multiple card you might consider adding a
shared group and putting its mainstack-specific stuff there.
- You could also consider moving the mainstack and all of the
substacks into a new mainstack which is kept fairly minimal; that
way all of your stacks have their own discrete space, and you still
have a mainstack to use as a central repository.
and two more ways :-)
- as Eric suggests, have a check in the preOpenStack handler to make
sure you are using the correct stack.
- have preOpenStack handlers in all your substacks (they can be empty
if you don't need to do anything), and don't "pass" them. That will
trap the preOpenStack handler message and stop it passing up the
hierarchy to the mainStack.
