how to make a file field to remember the file to upload after server validation fails?

Hi All,
I've set a large form with lots of fields and applied the PERSIST FORM data to populate all field and retain entered data after validation fails.
All text field, select, checkbox and textarea are fine but I cannot find a way to make FILE field to remember the file to upload when validation fails.
Is there a way to use PERSIST DATA in file fields?
TIA
tony

You can use the "Validated Entry" values from the bindings. If you need to use both, then add a url parameter to the failed validation in the server validations server behavior like: mypage.php?fail=1

Then you can use a conditional statement to show one value or the other like:

php:
<?php echo((isset($_GET['fail']))?[ValidatedEntryFromBindings]:[PersistentValue]); ?>

Hi Ray,
I cannot understand you reply completely.
So, I bind the validated entry to the file field and then?
What do you mean by "if you need to use both"?
TIA

You probably don't need to use both, so try binding to the validated entry and see if that is enough for you.

Sometimes if you allow people to go back to previous pages before storing in the database you may want to be able to use the persistent form value if it exists, but use the validated field value if the submit fails... that is what I mean by use both, really one or the other based on whether the form validation just failed or not.
