Hi,
I've found the problem, but it seems very odd to me. The issue was
actually (also?) the fact that the underlying bound property,
item.reportsTo, was null. I think the error message should indicate
that instead of a converter error? And why did it work with a manually
inserted (in the jsp) selectItem instead?
Thanks,

Hi Mike,
Thank you for your response. The component id10:... is the
f:selectItems component. If I comment that one line out then the jsp
generates normally.
The kinds of objects in the selectList are
javax.faces.model.SelectItem, with an Integer value and a String
label, using the constructor SelectItem(Integer value, String label).
The second dataTable in the code was included just to make sure they
in fact have the expected value and label fields, and that the fields
convert correctly when just using outputText.
Does that info help figure out what's going on?
Thanks,

Which component does the "_id10:display_0:_id22" string refer to?
Might help to put in some id attributes for the data tables and
selectOneMenu.
Also, what does ManageInterviewersBean.supervisors.selectList look
like? What kinds of objects are in the list? It sounds like your
"nearly identical" list returns Integers (which there's a default JSF
converter for), but your list here returns Supervisors, for which
there will be no default converter.
And this is bizarre, because I have a List of SelectItems, which is
nearly identical to another list that works fine elsewhere - Integer
value and String label (using new SelectItem(obj.getId(),
obj.getName()). As you can see in my JSP, I even produced another table
to make sure that no values or labels are crazy or null. Could someone
please help me?
JSP snippet:
<h:form styleClass="crudForm">
<h:commandButton styleClass="crudButton"
value="#{bundle.save_changes}"
action="#{ManageInterviewersBean.saveChanges}"/>
<t:dataTable id="display"
styleClass="table-background"
headerClass="table-header"
footerClass=""
rowClasses="row-odd,row-even"
var="item"
value="#{ManageInterviewersBean.interviewers.list}"
preserveDataModel="true"
sortColumn="#{ManageInterviewersBean.interviewers.sort}"
sortAscending="#{ManageInterviewersBean.interviewers.ascending}"
preserveSort="true">
<h:column>
<f:facet name="header">
<h:outputText value="#{bundle.supervisor}" />
</f:facet>
<h:selectOneMenu value="#{item.reportsTo.id}">
<%-- this next line causes the error! If commented out, the
next dataTable will work --%>
<f:selectItems
value="#{ManageInterviewersBean.supervisors.selectList}"/>
<%--<f:selectItem itemValue="1" itemLabel="Your Mom"/>--%>

<h:outputText value="#{item.value}"/>

<h:column>
<f:facet name="header">
<h:outputText value="#{bundle.name}" />
