Hi

This is my environment:

• Spring 3
• Richfaces 3.3.3
• JVM 1.6
• Apache tomcat 6.0.26

What i'ld love to do is a search, display the search resulta in an extended datatable where i'll show to the user 3 columns. The last columns is a checkbox and the user can choose one or more elements.

This is what i did:

search.xhtml:

<!-- Sezione Elenco -->
<h:panelGroup id="out" columns="4"> 
<!-- rich:panel id="panelRisultati" rendered="#{not empty engageRicercaReferenzeController.cmdRicerca.listaSchedeProgetti}">  -->
<rich:panel id="panelRisultati" rendered="#{engageRicercaReferenzeController.numAnn>0}">
<a4j:form id="thisFormRicLista">
<rich:extendedDataTable value="#{engageRicercaReferenzeController.dataModel}"
var="lista" id="table" width="800px" height="350px"
sortMode="#{engageRicercaReferenzeController.sortMode}"
noDataLabel="#{msg.nessunRisultato}"
selectionMode="#{engageRicercaReferenzeController.selectionMode}"
tableState="#{engageRicercaReferenzeController.tableState}"
selection="#{engageRicercaReferenzeController.selection}" 
rows="#{engageRicercaReferenzeController.numeroRecordPerPagina}"
styleClass="noBorderTable" rowKeyVar="row">
<f:facet name="header">
<h:outputText value="#{msg.elencoRicerca}" />
</f:facet>
<rich:column width="350px" id="titolo" sortable="false">
<f:facet name="header">
<h:outputText value="#{msg.titolo}" />
</f:facet>
<a4j:commandLink  id="detaillink"
oncomplete="javascript:Richfaces.showModalPanel('dettaglioPrg',{width:600,height:500})"
action="#{engageDettaglioReferenzeController.detailRefPrg}" reRender="dettaglioPrg"> >
<f:param name="idRefPrg" value="#{lista.id}" />
<h:outputText value="#{lista.titoloProgetto}" />>
</a4j:commandLink>
<rich:toolTip for="detaillink" direction="top-left"
value="Dettaglio Progetto" />
</rich:column>
 
<rich:column width="300px">
<f:facet name="header">
<h:outputText value="#{msg.contattoInterno}" />
</f:facet>
<h:outputText value="#{lista.contattoInterno}" />
</rich:column>
<rich:column width="100px">
<f:facet name="header">
<h:outputText value="#{msg.dataInizio}" />
</f:facet>
<h:outputText value="#{lista.dataInizio}">
<f:convertDateTime dateStyle="short" timeZone="Europe/Berlin"
pattern="dd/MM/yyyy" type="both" />
</h:outputText>
</rich:column>
 
<rich:column width="100px">
       <h:selectManyCheckbox id="checkboxschede" value="#{engageRicercaReferenzeController.cmdRicerca.schedeProgettoSelezionate}">
                             
                             <a4j:support ajaxSingle="true" 
                                               event="onchange" 
                                               actionListener="#{engageRicercaReferenzeController.checkboxListener}" 
                                               />
                             <f:selectItem itemValue="#{lista.id}"/>
                         </h:selectManyCheckbox>
                        
</rich:column>
 
 
</rich:extendedDataTable>
<rich:datascroller align="left" for="table" id="sc2" immediate="true"
page="#{engageRicercaReferenzeController.scrollerPage}" />
 
<h:panelGrid columns="3" title="Download report" id="reportDownload">
<f:facet name="header">
                       <h:outputText value="Scarica"/>
                     </f:facet>
<a4j:htmlCommandLink action="#{engageRicercaReferenzeController.downloadFile}">
<f:param name="tipoFile" value="pdf" />  
<h:outputText value="Download in formato pdf" />
</a4j:htmlCommandLink >
<a4j:htmlCommandLink action="#{engageReportRicerca.downloadFile}">
<f:param name="tipoFile" value="xls" />  
<h:outputText value="Download in formato excel" />
</a4j:htmlCommandLink >
<a4j:htmlCommandLink action="#{engageReportRicerca.downloadFile}">
<f:param name="tipoFile" value="rtf" />  
<h:outputText value="Download in formato rtf" />
</a4j:htmlCommandLink >
</h:panelGrid>
</a4j:form>
</rich:panel>
</h:panelGroup>

Well the query is executed correctly; the table is shown correctly and the checkbox too.

The variable "lista" is an object taken from the database; this object has some properties between them there is the id property that is a long (primitive object). Well when i select a checkbox i get this error:

13-lug-2010 17.32.21 com.sun.faces.lifecycle.RenderResponsePhase execute
INFO: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=thisFormRicLista:table:1:checkboxschede[severity=(ERROR 2), summary=(thisFormRicLista:table:1:checkboxschede: Validation Error: Value is not valid), detail=(thisFormRicLista:table:1:checkboxschede: Validation Error: Value is not valid)]

When i deselect the checkbox no message is shown.

Do you have any suggestion on how i can solve this issue?

Angelo.
