I think generally you will have to re-create the filter col selector if you want to change the data table which it is related to. I don't use Application Builder so here is example how it could look like (in very simple case) as JMP script
Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
nw = New Window("Filter Col Selector Example",
fcs_collector = V List Box(
vlb = V List Box(
fcs = Filter Col Selector(dt)
)
)
);
wait(1);
dt2 = Open("$SAMPLE_DATA/Probe.jmp");
vlb << Delete Box;
fcs_collector << Append(vlb = V List Box(
fcs = Filter Col Selector(dt2)
));
