Question

I have a problem with my datatable, I want display the information of a datatable’s row when selecting it, for that I created a value called currentChangerStatus I wanted to set it to the current selection, here is my code:

<p:dataTable id="projets"  var="p" value="#{projet.init()}" rowSelectListener="#{projet.currentChangerStatus(currentChangerStatus)}" selectionMode="single" onRowSelectStart="datecreation">  

                                    <f:facet name="header">  
                                            Listes des projets Gpsi  
                                        </f:facet>  

                                        <p:column>  
                                            <f:facet name="header">  
                                                <h:outputText value="Code" />  
                                            </f:facet>  
                                            <h:outputText value="#{p.projets.codeProjet}" />  
                                        </p:column>  

                                        <p:column>  
                                            <f:facet name="header">  
                                                <h:outputText value="Intitulé" />  
                                            </f:facet>  
                                            <h:outputText value="#{p.projets.libelle}" />  
                                        </p:column>  


                                    </p:dataTable>  

the bean:

 public void setCurrentChangerStatus(ChangerStatus currentChangerStatus)
{
    this.currentChangerStatus=currentChangerStatus;
}
  public ChangerStatus getCurrentChangerStatus()
{
        return currentChangerStatus;
    }

the problem is that the datable is not accepting this expression :

rowSelectListener="#{projet.currentChangerStatus(currentChangerStatus)}"

This is other way to display the information of a datatable’s row.

<p:dataTable>
.....
.....
   <p:column>
    <p:commandLink update="xhtmlElementID" title="View Detail"  >
                     <p:graphicImage value="/images/search.png" />
                   <f:setPropertyActionListener value="#{p}" target="#{project.SomeObject}" />
         </p:commandLink>
</p:column>
</p:dataTable>

here target=”#{project.SomeObject}” is the Data to be updated when you cleck on command link
