Description | Handle the openBackground message to change a group's objects, or perform other updates, when a card with the group on it is opened. The openBackground message is sent to background groups, if there is more than one group on the card, the openBackground message is sent to each one. The openBackground message is sent after the destination card is visible. To make changes that take effect before the card becomes visible on the screen, use the preOpenBackground message instead. The actual navigation is not triggered by the openBackground message, so trapping the message and not allowing it to pass does not prevent the card with the group from opening.
