I think that when you open the library stack, RR is sending an "openstack" - the library stack has no such handler but because it is now a proper sub-stack, the application's "opencard" handler is in the path, so it is being run instead. ?!

Is that what would happen ?
If so - what's the standard technique to deal with it ? An empty "openstack" handler ?
And should there, therefore, also be empty "preopenstack", "opencard", etc. handlers in any library stack, least it become a sub-stack and subsequent;y cause a problem like this ?


I have a standard set of dummy handlers that I routinely paste into each substack's stack script to avoid this problem: preOpenStack, openStack, closeStack and the same for the card messages.

Also, if possible I put initialization handlers like this in the card scripts rather than the stack scripts. This works fine for single card stacks, but not if there are multiple cards.

Cheers,
Sarah
