Trinidad: JSF 2.0 f:selectItems do not work inside tr:selectManyCheckbox

[Admirolas <ad...@gmail.com>]

Hello,

I have noticed, that JSF2.0 extended tag f:selectItems do not work 
inside trinidad's tr:selectManyCheckbox tag. Here is my example:

<tr:selectManyCheckbox label="#{bundle.roles}"
                         value="#{userBean.roles}" >
<f:selectItems value="#{rolesBean.roles}" var="role"
                             itemValue="#{role}" 
itemLabel="#{role.aprasymas}"
                             itemDisabled="false" itemLabelEscaped="true"
                             itemDescription="#{role.aprasymas}" />
</tr:selectManyCheckbox>

After trying to view this page, I get ClassCastException, that says, 
that can not cast to SelectItem. But us much, us I understand JSF2.0 
f:selectItems tag allows to pass POJO's.

If i substitute tr:selectManyCheckbox to h:selectManyCheckbox it renders 
correctly. But i want to use the one from trinidad lib.

Is this a bug? Or I'm missing something?
