I have a question related to this thread.
In my app I have two pages: pgA and pgD, and pgA is an ancestor for pgD.
Both pages have code in this_onBeforeDisplay() event, so when I load pgD,
NetDynamics executes code in this event in pgA, then in pgD. Most of the
time it's what I need, but sometimes I only need to execute
pgD.onBeforeDisplayEvent() and not interested in ancestor's script. I am
wondering if there is a way to
sort of "turn it off". If some of you out there are familiar with
PowerBuilder, I am looking for a way to for the descendant to "override"
ancestor script, as oppose to "extend" it.
Thanks -
