CFDIV binding problem

Question

I'm trying to create a MS Outlook interface using cf8 ajax
feature and I can't seem to figure this error out. I get
Elemet not
found : myInbox. How do I pass a variable from one cfdiv to
another. I hightlighted the problematic line.
<cfset rightNow = Now()>
<cfset lastWeek = DateAdd("d","-7", rightNow)>
<cfajaximport tags="cfgrid, cfdiv">
<script>
var myInbox.uid
</script>
<cfexchangeconnection
action="open"
username ="myusername"
password="and password"
server="mail.myserver.com"
connection="testconn1" protocol="https">
<cflayout type="border" style="border:1px solid red;">
<cflayoutarea position="left" style="width:250px">
<cfform format="html">
<cftree format="html" name="mailfolders">
<cftreeitem value="Mailbox" expand="yes">
<cftreeitem parent="Mailbox" expand="yes" value="Inbox"
/>
<cftreeitem parent="Mailbox" expand="yes" value="Deleted
Items" />
</cftree>
</cfform>
<cfdiv bind="content.cfm?value={mailfolders.node}" />
</cflayoutarea>
<cflayoutarea position="center" style="width:100%">
<cflayout type="border">
<cflayoutarea position="top" style="height:400">
<cfdiv
bind="url:mailfolder.cfm?mailfolder={mailfolders.node}" />
</cflayoutarea>
<cflayoutarea position="center" >
<cfdiv
bind="url:message.cfm?uid={myInbox.toid}" />
</cflayoutarea>
</cflayout>
</cflayoutarea>
</cflayout>

As you have figured out, the value of the edit_field will not change until it is validated and it will only be validated with every keystroke when "immediate = true".
Another way to accomplish this would be to bind the enabled state of the button to the value of the edit field. Such as:
enabled = LrView.bind {
     key = "text",
     transform = function( value, fromTable )
          if fromTable then
               if value ~= nil and value ~= "" then
                    return true
               end
               return false
          end
     end
(This was not tested but should be close)
The advantage of this is that the button will be enabled and disabled without the validation of the edit_field needing to be called. So if the value of the text field is changed programatically the button will be updated.
