Question

I am getting the following error when I select a row in the lazy datatable :
javax.faces.FacesException: Method not found: com.gestion.projet.web.jsf.ProjetComponentImpl#f632823.onRowSelect(org.primefaces.event.SelectEvent)

and then the code associated with the following bean method:
#Scope("session")
#Component("ProjetComponent")
public class ProjetComponentImpl implements ProjetComponent {
public void onRowSelect(SelectEvent event) {
FacesMessage msg = new FacesMessage("Projet Selected", ((Projet) event.getObject()).getIdprojet().toString());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
and this the xhtml page:
<h:form id="form">
<p:dataTable var="current" value="#{ProjetComponent.lazyModel}"
paginator="true" rows="10"
paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}"
rowsPerPageTemplate="5,10,15" selectionMode="single"
selection="#{ProjetComponent.projet}" id="projetTable" lazy="true">
<p:ajax event="rowSelect" listener="#{ProjetComponent.onRowSelect}"
update=":form:projetDetail" oncomplete="PF('projetDialog').show()" />
<p:column headerText="Id" sortBy="#{current.idprojet}" filterBy="#{current.idprojet}">
<h:outputText value="#{current.idprojet}" />
</p:column>
<p:column headerText="Nom" sortBy="#{current.nomprojet}"
filterBy="#{current.nomprojet}">
<h:outputText value="#{current.nomprojet}" />
</p:column>
</p:dataTable>
<p:dialog header="Projet Detail" widgetVar="projetDialog" modal="true"
showEffect="fade" hideEffect="fade" resizable="false">
<p:outputPanel id="projetDetail" style="text-align:center;">
<p:panelGrid columns="2"
rendered="#{not empty ProjetComponent.projet}"
columnClasses="label,value">
<f:facet name="header">
</f:facet>
<h:outputText value="Id:" />
<h:outputText value="#{ProjetComponent.projet.idprojet}" />
<h:outputText value="Nom:" />
<h:outputText value="#{ProjetComponent.projet.nomprojet}" />
</p:panelGrid>
</p:outputPanel>
</p:dialog>
</h:form>
this is a snaphshot of what i get when i select a row :

Seems you're interchanging Spring Annotations with JSF annotations - PrimeFaces is a JSF component library in use with a JSF Managed Bean - #SessionScope and #ManagedBean(name="projectBlah")
from the javax.faces.bean packages
