I tried to reproduce this with the latest and greatest and could
not... Specifically, the following page:
<?xml version="1.0" encoding="iso-8859-1" standalone="yes" ?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:tr="http://myfaces.apache.org/trinidad" >
<jsp:directive.page contentType="text/html;charset=utf-8"/>
<f:view>
<tr:document>
<tr:form>
<tr:panelGroupLayout layout="vertical">
<tr:selectOrderShuttle id="foo" label="Cars"
valueChangeListener="#{list.valueChanged}"
value="#{list.selectedCars}">
<f:selectItems value="#{list.makes}"/>
</tr:selectOrderShuttle>
<tr:message for="foo"/>
<tr:commandButton text="Submit"/>
</tr:panelGroupLayout>
</tr:form>
` </tr:document>
</f:view>
</jsp:root>
... in the demo bundle. That's f:selectItems where
value is a List<Car>, and the SelectItems have Car
objects as their values.

That's very disconcerting; this could be a recently introduced
bug (I redid the implementation of the shuttle renderers). I'll
have to build up a little testcase and see what's what. You're
using a recent build, right?
