Bug 12285 – File input value not copied on cloneNode()

• Component: Forms
• Status: RESOLVED DUPLICATE

[Jeremy Nicoll]

Example: 

<script type="text/javascript">
        function press_this () {
                var f = document.getElementById('upload_1');
                var f2 = f.cloneNode(true);
                document.getElementById('form2').appendChild(f2);
        }
</script>

<form action="test.php" method="POST" enctype="multipart/form-data">
        <input type="file" name="upload" id="upload_1"/>
</form>

<input type="button" onclick="press_this();"/>
<form action="test.php" method="POST" id="form2" enctype="multipart/form-data">

</form> 
--------------------------------
   The selected value is not copied with cloneNode() in either the latest version of Safari or the Webkit nightly.  It works properly in Firefox and Opera, but not in IE7.

If you test with the inspector, you'll see that the file input value *is* copied on cloneNode in TOT. So this has already been fixed. The reason you can't see the new value is the problem reported in bug 12273. So you can either consider this "already fixed" or a duplicate. I'm going to resolve it as a duplicate since the test case works fine with the fix I've attached to the other bug.

Sorry for asking you to report a new bug and then marking it as a duplicate!

That's ok - as a developer myself I know that it can take a while to track down a bug and find out what it actually is.
