Release 10.1A: OpenEdge Development:
ADM Reference

isUpdateActive

Procedure that is received as a publication from container source to check whether contained objects have unsaved or uncommitted changes, including addMode.

Location: data.p

Parameters:

INPUT-OUTPUT plActive AS LOGICAL

FALSE if the ContainerTargets should be surveyed.

Notes:

This is published thru the container link from canExit for close logic (ok, cancel, exit). It is very similar to canNavigate -> isUpdatePending, which is published thru the data link.
We currently ONLY check rowObjectState as the other states are checked in the visual objects.
