Property 'bnr' not found on type org.hibernate.collection.PersistentSet
Hi,
i have an DataTable:
<h:dataTable id="bestellungenTabelle" value="#{kunden.detailsKunde.bestellungen}"
var="best" cellspacing="5"
rendered="#{not empty kunden.detailsKunde.bestellungen}">
<h:column>
<f:facet name="header">
<h:outputText value="Ordernr"/>
</f:facet>
<h:outputText value="#{best.bnr}"/>
</h:column>
</h:dataTable>
kunden is mapped in an XML File:
<managed-bean-name>kunden</managed-bean-name>
<managed-bean-class>de.bm.kundenverwaltung.ui.KundenBean</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
Here the variables in the ManagedBean (KundenBean):
private Kunde detailsKunde;
bestellungen is an Collection in Kunde, but when i call the jsp page i get the message:
'#{best.bnr}' Property 'bnr' not found on type org.hibernate.collection.PersistentSet
Here is the full stack trace:
