Actually, I'm using an array based ListBox, but your comment led me to
understand how I should apply the underlying concept of what you were getting
at.
I added this code to the appropriate locations, to reestablish the selection in
the child table and then propagate that data into the arrays being displayed in
the ListBox.
QUERY([table];[table]ID=[LinkedTable]ID)
SELECTION TO
ARRAY([table];Numbers;[table]EndpointType;Names;[table]EndpointAddress;Addresses)
Now the ListBox updates as desired.
Thanks so much for helping understand what I was missing.

Subject: Re: UI Form Updates
asumming the listbox is a selection listbox there is a set associated
with the listbox which represents the selected record(s). The listbox
property is called 'highlight set'.
This set (i am going to call it "Selected_Set") holds all record(s)
selected by the user.
So your code is much easier done like this:
// the user has selected at least 1 record
if Records in set("Selected_Set")>0)
Create set([AccountSOAPEndpoints];"$Temp") //holds all currently
displayed records
CONFIRM("Are you SURE you want to remove the selected Web Service
Endpoint?";"Remove";"Cancel")
If (OK=1)
//places the selected record(s) into the current selection
use set("Selected_Set")
// assuming the records are not locked by another user/process they
are deleted
delete selection([AccountSOAPEndpoints])
// this removes the deleted records from the originally displayed
records
// and places the resulting set into "$Temp"
difference("$Temp";"Listbox_Selection_Set";"$Temp")
// this places the originally displayed records, minus the deleted
ones
// into the current selection of [AccountSOAPEndpoints]
// this should update the listbox
use set("$Temp")
clear set("$Temp") // clear the set to avoid excess memory usage
end if
end if
your code would:
// create a set with the originally displayed records
> CREATE SET([AccountSOAPEndpoints];"$TempSet")
//retrieve all records into current selection
> ALL RECORDS([AccountSOAPEndpoints])
/replace the current selection (all records) with the originally
displayed records
> USE SET("$TempSet")
> CLEAR SET("$TempSet")
