I have this form, the line comboBox is suposed to be regenerated when changing the range one.
This is done with a4j from richfaces.

The form

It was working fine until I made it into a facelet component, here is my code :

Bean

@Getter
@Setter
@ManagedBean(name = "creerProduit")
@SessionScoped
public class CreerProduitBean implements Serializable {
    /** serial uid genere par eclipse */
    private static final long serialVersionUID = 7901115336087748268L;

    /** contenu des comboBox */
    private List<Gamme> listeGammesAffichables;// ce que contient la combox
    private List<Famille> listeFamillesAffichables;// ce que contient la combobox
    private List<Fournisseur> listeFournisseurAffichables;// ce que contient la combobox

    /** liste de toute les familles pour nos calculs */
    private List<Famille> listeFamilles;// la liste de toutes les famille (pour calculs)

        // recuperation de toute les gamme et famille afin de

    /**

               g = listeGammesAffichables.get(i);
           }
       }

           }
       }

       f.setGamme(g);
       p.setFamille(f);

       d.create(p);

       return "../vues/rechercherProduit.xhtml";    
    }

            }
        }
    }
}

                        immediate="true" /></span>
            </div>
</ui:composition>

And here is how I call it in the jsf page :

<mytaglib:cmProduit 
                nomGamme="#{creerProduit.nomGamme}"
                listeGammesAffichables="#{creerProduit.listeGammesAffichables}"
                nomFamille="#{creerProduit.nomFamille}"
                listeFamillesAffichables="#{creerProduit.listeFamillesAffichables}"
                nomFournisseur="#{creerProduit.nomFournisseur}"
                listeFournisseurAffichables="#{creerProduit.listeFournisseurAffichables}"
                designation="#{creerProduit.designation}"
                txRecu="#{creerProduit.txRecu}"
                txVerseCGP="#{creerProduit.txVerseCGP}"
                txVerseDR="#{creerProduit.txVerseDR}"
                txIncompressible="#{creerProduit.txIncompressible}"
                indications="#{creerProduit.indications}"
                filterFamily="#{creerProduit.filterFamily}"
                 />

And when I redefine range, my tomcat is saying this :

GRAVE: /WEB-INF/forms/formProduit.xhtml @34,43 valueChangeListener=”#{filterFamily}”: /vues/creerProduit.xhtml @56,8 filterFamily=”#{creerProduit.filterFamily}”: Property ‘filterFamily’ not found on type com.me.web.beans.produit.CreerProduitBean
javax.faces.event.AbortProcessingException: /WEB-INF/forms/formProduit.xhtml @34,43 valueChangeListener=”#{filterFamily}”: /vues/creerProduit.xhtml @56,8 filterFamily=”#{creerProduit.filterFamily}”: Property ‘filterFamily’ not found on type com.me.web.beans.produit.CreerProduitBean

any idea why I can’t call this method?

That’s not a composite component. That’s also not a custom component. That’s a tag file. You need to declare the attribute as a method expression using <method-signature> in the .taglib.xml file. Otherwise it will default to a value expression which expects a property with a getter/setter.

<attribute>
    <name>filterFamily</name>
    <method-signature>void method(javax.faces.event.ValueChangeEvent)</method-signature>
</attribute>

In a real composite component, you can declare it as <cc:attribute method-signature> instead.

<cc:attribute name="filterFamily" method-signature="void method(javax.faces.event.ValueChangeEvent)" />
