hihi Henner,
i like the 'list_and_single' type forms and i basically use these all the time.
i have taken these templates and modified them to be 'all-in-one' functional
forms (list/search, update, delete, insert).
the problem is if there is an insert error, the page will be redrawn with the
error message(s), but without any records at all. that is, the user may be
paginating through the table records and on the fifth pagination page decide
to insert a new record. however if the insert does not pass validation then
the user loses their current 'position'; the page is becomes empty basically
and there are no navigation buttons at all (first/previous, next/last).
i found out it is because of the following DbFormTag code:
if ((webEvent != null)
&& EventType.EVENT_DATABASE_INSERT.equals(
webEvent.getType()) && (errors != null)
&& (errors.size() > 0)
&& (webEvent.getTable().getId() == getTable().getId())) {
// error in insert event, nothing to do!
navEvent = null;
resultSetVector = null;
setFooterReached(true);
}
because navEvent is set to null and the footer flag is set to true, this causes
no table data to be displayed.
on my forms, i don't use any subforms at all, so i have no child fields. all
fields are from one parent table.
i want to be able to re-load/re-display all the current table data (like
PageReloadEvent does), even when there are insert errors. but i'm not sure
what other 'flags' or conditions i can modify in the code to do this, and
without
breaking the current behaviour...
any advice?
thanks in advance!
woodchuck
