<para>This example illustrates how you can programmatically update the
content of a selection list using a collection built in the flow.</para>
<para>
This sample illustrates event-handling in Woody and how selection lists
can be changed
programmatically.
</para>
<para>
Event-handlers are defined in the form definition to update the selection
lists and set
the comment text below the table. This requires only a few lines of
server-side JavaScript.
Selection widgets also have a "submit-on-change" attribute set in the
form template so that
changes are considered immediately by the server.
</para>
<para>
See "countryselector_form.xml" and "countryselector_template.xml" to see
how this is done.
