When you have a hidden field on a page, and then you change the value of the field in javascript.  The field is no longer visible via the getElementsByAttribute method.



Reproducible: Always

Steps to Reproduce:
1.Open attached test file
2.click the buttons I have layed out in order
3.The value goes from 0 to 1 but then the item can't be found by the attrbiute

Actual Results:  
the hidden item goes away.

Expected Results:  
the hidden item should still be found in the 

I will attach a test file to demonstrate the error.  Follow the buttons on the page they are in order.

If the attachment doesn't work here is the xul file:

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window
    id="Test"
    title="Test"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
    >


    <script>
      <![CDATA[
			function showObjId() {
			   alert("Value: " + document.getElementById("objId").getAttribute("value") + "     Form: " + document.getElementById("objId").getAttribute("form"));
			}
			
			function setObjId() {
			   document.getElementById("objId").setAttribute("value","1");
			   alert("Value Set To 1");
			}

			function showItemsLength() {
				var items = document.getElementsByAttribute("form","test");
				alert("Items: " + items.length);
			}
			
			
			]]>
    </script>

		
	<label hidden="true" value="" id="objId" form="test" />

	<button label="1. Show Value" onclick="showObjId()" />
	<button label="2. Show Items" onclick="showItemsLength()" />
	<button label="3. Set Value" onclick="setObjId()" />
	<button label="4. Show Value" onclick="showObjId()" />
	<button label="5. Show Items" onclick="showItemsLength()" />
	

</window>

test case file

ignore the overlays, they were from a file that I use in my application. Sorry for leaving them in, but they don't effect the outcome.

Any news on this. I run a software company (Med-Track.net) that depends on xul and the gecko engine (FireFox is our browser of choice), and this is a big problem for me.   I am sure you guys are slammed with the release of 2.0.  If I can help please let me know.

Thanks

Move all DOM bugs that haven't been updated in more than 3 years and has no one currently assigned to P5.

Hi Hsin
would it be ok to resolve this really old bug?
i think mozilla dropped XUL some years ago, i can´t open the file attached on this bug
