Right, I got that. So my question was "Is being able to bubble up events to the older grabbers intended (given the use of 'stack') and whether it is safe?", which you answered below. > Does this make sense?

Perhaps the luadoc for the module should describe the event bubbling behavior too. -- Anurag Priyam -- To unsubscribe, send mail to awesome-devel-unsubscr...@naquadah.org.
