Jessica,
Because you are using Trinidad 1.0.1, you'll need to use the tr:document or trh:html/head/body tags to ensure the iframe mechanism is in place. Iframes are used in 1.0.1 to handle PPR, while versions 1.0.3+ use XmlHttpRequest.

According to the TLD, SelectManyListBox doesn't have partialSubmit http://myfaces.apache.org/trinidad/trinidad-api/tagdoc/tr_selectManyList box.html and I get this exception when trying to use it org.apache.jasper.JasperException: Attribute partialSubmit invalid for tag selectManyListbox according to TLD I am using autoSubmit, as suggested in this tutorial: http://wiki.apache.org/myfaces/Partial-page_rendering but as I said earlier, it is re-rendering the whole page.
