Hi,
I've had this problem or something very like it in the past, but I
could never reproduce it. I think that sometimes RunRev gets itself
in a state whereby it creates a "rouge" object and that objects
causes all kinds of side-effects.
If you still have the errant stack, I suggest you send it to RunRev
support as it may have some tell-tale signs that would allow them to
trace where the object is coming from.
All the Best

Has anyone ever seen this?
(Tried on Rev 2.6.1, 2.7.x on Mac OSX; Rev 2.7 on Win XP)
I have a stack in which I am accessing a mysql database and
displaying lots of unicode text. I noticed that my openCard and
closeCard handlers on one of the cards weren't being executed on
moving between cards. I did some investigating using the message
watcher and noticed the following:
- When I first open the stack I get the expected sequence of card
and stack messages:
preOpenBackground
preOpenCard
openStack
openBackground
openCard
-When I go to the next card, either via a button handler or a View
menu shortcut, I get:
closeCard
preOpenBackground
That's all.
From this point on I get no open or close (including preOpen/Close)
messages sent to cards or backgrounds.
Then I tried creating a new card with nothing on it except go next
and go prev buttons, and set that card to be card 1.
- Again when I first opened the stack I got the normal sequence of
open/close messages.
- When I go from the blank card to any other card OR from any other
card back to the blank card I get the expected:
closeCard
preOpenCard
openCard
- However, when I go from any of the other cards to any card except
the blank one I see:
closeCard
preOpenBackground

OKAY, while I was composing this email I noticed that one of the
cards contained a rogue group, one I don't remember creating and
which had the same name of an image object on the card. The group
had no objects in it. Once I deleted this group the open and close
messages began working again. I decided to send this along anyway
for you all to tuck into the back of your brains as something to
check if your open and close messages ever stop working.
