(Firefox :: General, defect)

Description

[Andy Harris]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8

After refresh (F5) selected attribute of <option> not properly evaluated.
Note, proper behaviour after Control-F5, and on initial load of page.

Consider the following, copied from Firebug display:

<select name="ds" onchange="doSet(this,1)">
<script>
</script>
<option value="0">building1</option>
<option value="1" selected="">building2</option>
<option value="2">building3</option>
<option value="3">building4</option>
<option value="4">building5</option>
<option value="5">building6</option>
<option value="6">building7</option>
<option value="7">building8</option>
</select>

On initial load display shows "building2"   --- correct
On F5 refresh: "building1"                  --- incorrect
On Ctrl-F5: "building2"                     --- correct

Code that writes the select options:

function writeOpts(sel)
{
	for (i=0;i<datanames.length;i++)
        {
        if (i != sel)
            {
            opt = "<option value='" + i + "'>" + datanames[i] + "</option>" ;
            document.write(opt)
            }
        else
            {
            opt = "<option selected value='" + i + "'>" + datanames[i] + "</option>" ;
            document.write(opt)
            }
        }
}

Other browsers tested:
Opera -- All good
Safari -- All good
Chrome -- All good
IE -- All Good

Reproducible: Always

Steps to Reproduce:
1. JS writes select with options, option other than first has 'selected' attribute
2. Load page -- see all is good
3. Use F5 -- see that first option is pre-selected in error
4. Use Crtl-F5 -- see that correct option is pre-selected
Actual Results:  
AS above

Expected Results:  
Always show option wirh selected attribute

Checked:

http://www.w3.org/TR/html401/interact/forms.html

which just shows the selected attribute present.  The fault also occurs when the JS writes selected='true'
