Hi,
Thanks for the reply. The form has a SingleSelectField with names
that come from a database query. It also has a TextField to allow the
user to enter the name if the desired name isn't already in the
database/SingleSelectField. So if the user enters a new name in the
TextField, I would like the SingleSelectField to contain the name they
just entered after the redirect occurs (don't need to point to it, it
just needs to one of the selectable names). The SingleSelectField is
populated in the TableForm class and I can't seem to get the code to
rerun prior to the redirect. The correct table is being updated, if I
restart the application the new name shows up in the
SingleSelectField.
I pasted the code from the TableForm class and the functions for the
pages here:

Thanks,
Eric
