Table Validation - Report errors without losing changes

Question

Hi all,
I am experimenting with table validation based on Denes Kubicek's example at http://apex.oracle.com/pls/otn/f?p=31517:41. I have had no problems getting this working,
but I need to stop if loosing data when the validation rules are not met.
If I have 10 rows in my table and the user updates 6 of these with valid new values and 1 with an invalid value then the submit button causes the error message to be shown as expected, but the page / table reverts back to the data from the databse and all the other changes are lost.
How can I get the page to keep the entered values when the page is refreshed?
Thanks,
Martin

Martin,
You may need to replace the validation using JS. JS equivalent for Denes e.g.
Put this in page HTML Header..
<script type="text/javascript">
function f_validate()
     var comm;
        var dept;
        var err ='';
     for (i=0;i < document.wwv_flow.f02.length;i++)
     comm = document.wwv_flow.f07.value;
     dept = document.wwv_flow.f08[i].value;
     if (comm > 2000 && dept == 20)
          err = err + 'Error at Row ' + i;
if (err == '')
doSubmit();
else
alert (err);
document.wwv_flow.f07[0].focus();
</script>
Change the 'Submit' button target to URL and type javascript:f_validate(); as URL Target
Cheers,
Hari
