autocomplete in add/edit form

Hi all

I would like to use the browser autocomplete functionality, i was using javascipt to turn that feature on ( only for two fields )

$(document).ready(function()
{
$('#field-name').live('focus',function()
{
$(this).attr('autocomplete', 'on');
});


$('#field-street').live('focus',function()
{
$(this).attr('autocomplete', 'on');
});
});

if i click with the mouse on one of the two fields i get a dropdown list with some suggestions, i can choose one and autocomplete seems to work, but ! ....

New name values or street values are not cached !? --> Only latest Opera does, so my question is, what could it be to prevent new values to be stored in cache ? Is there a Javascript function that fires on submit which dissables autocomplete ? I didn't found anything ...

If i change the id of the form, it works but then i lose form functionality ( off corse )

RG and thx in forward
