Couple of things to try...
1. Use this constructor for the new options...
opener.#attributes.formname#.previewMenu.options[#(i-1)#] = new
Option('Test','Test',0,0)
2. Are you sure 'opener' is referencing the right point in the DOM - off
the top of my head opener is a window object, whereas forms live in a
document object, or in other words, try opener.document.form etc. Use
alert('string') to make sure these objects exist - i.e
alert(opener.document) should result in a popup with [object] rather than an
error.

Hi
I have a form that when submitted opens a popup that uploads an image.
The directory where the image is stored is the retrieved with
cfdirectory and a select object in the opener populated with the new
list of files.
At least that is what is supposed to happen. I can't get the select in
the opener to display the new list.
My CF code in the popup is this:
<cfdirectory directory="#attributes.sourceFolder#"
name="directoryListing" action="list" filter="*.jpg|*.gif">
<Cfoutput>
<script language="JavaScript" type="text/javascript">
<!--
opener.#attributes.formname#.previewMenu.options.length = 0;
<cfloop index="i" from="1" to="#directoryListing.recordcount#">
<!---opener.#attributes.formname#.previewMenu.options[#(i-1)#] = new
Option("#directoryListing.name[i]#","#request.imageMagick.width#:#reques
t.imageMagick.height#")--->
opener.#attributes.formname#.previewMenu.options[#(i-1)#] = new
Option('Test')
</cfloop>
window.close();
//-->
</script>
</Cfoutput>
The source that appears in the popup is:
<script language="JavaScript" type="text/javascript">
<!--
opener.frmDynamicPage.previewMenu.options.length = 0;
opener.frmDynamicPage.previewMenu.options[0] = new
Option('Test')
opener.frmDynamicPage.previewMenu.options[1] = new
Option('Test')
opener.frmDynamicPage.previewMenu.options[2] = new
Option('Test')
opener.frmDynamicPage.previewMenu.options[3] = new
Option('Test')
window.close();
//-->
</script>
I get a javascript error of "The server threw an exception". IE usually
then crashes and closes the popup (the window.close() doesn't work.
The select box is however cleared so the first line setting the length
to 0 works.
In the opener I have this button:
<input type="button" value="test"
onClick="this.form.previewMenu.options[this.form.previewMenu.options.len
gth] = new Option('Test')">
that works fine.
I'm lost - hope someone can help.
Thanks
