selectManyMenu and EntityHome
I successfully used, the EntityHome generated by seam-gen with selectOneMenu like this:
<h:selectOneMenu value="#{companyHome.instance.state}"
converter="#{converters.stateConverter}">
<s:selectItems value="#{stateList.resultList}" var="state"
label="#{state.name}" noSelectionLabel="Please Select..."
hideNoSelectionLabel="true" />
</h:selectOneMenu>
But when I try to use the same technique with a Collection, it throws an exception:

My question is, is it not possible to use the generated entity homes like so:
<h:selectOneMenu value="#{companyHome.instance.states}"
converter="#{converters.stateConverter}">
<s:selectItems value="#{stateList.resultList}" var="state"
label="#{state.name}" noSelectionLabel="Please Select..."
hideNoSelectionLabel="true" />
</h:selectOneMenu>
if states is a Collection?
