This is vanilla
JSF not ICEFaces, but I guess it'll be more or less the same.
In your
JSP:
If you want the submission to occur immediately you make the selection, you can optionally add
onchange="this.form.submit();" as an additional attribute to the selectOneMenu tag .
In your managed bean, the ValueChangeListener method is called
listen, the output property is called
speak, which will appear in the outputText field above, and the SelectItem List is called
possible (and it's up to you to fill it).
