Ext Window in a CFFORM tag

Guys,

I have a problem with the ext window and I dont know how I resolve this.

How put a ext window inside a cfform tag?

Example:

<ext:window id="settings" title="..:: Upload ::.." width="500" height="200" iconCls="settings" modal="true" resizable="true" closeAction="hide" source="http://localhost:8500/upload.cfm">

How I call the ext window in a cfform tag in the event onSubmit?

tks
