my bean categorymb :
package managedbean; import entitybean.item; import entitybean.translatecategory; import java.util.list; import javax.ejb.ejb; import javax.faces.bean.managedbean; import javax.faces.bean.managedproperty; import javax.faces.view.viewscoped; import sessionbean.itemfacadelocal; import sessionbean.translatecategoryfacadelocal; /** * * @author aurélien */ @managedbean @viewscoped public class categorymb { @ejb private itemfacadelocal itemfacade; @ejb private translatecategoryfacadelocal translatecategoryfacade; @managedproperty("#{internationalizationmb}") private internationalizationmb language; private list<item> listitems; /** * creates new instance of categorymb */ public categorymb() { } public list<translatecategory> getcategories () { return translatecategoryfacade.findbylanguage(language.getlocale().getlanguage()); } public void getitemsbycat (int idcat) { setlistitems(itemfacade.findbycat(idcat)); } public internationalizationmb getlanguage() { return language; } public void setlanguage(internationalizationmb language) { this.language = language; } public list<item> getlistitems() { return listitems; } public void setlistitems(list<item> listitems) { this.listitems = listitems; } } and bean itemmb :
package managedbean; import javax.enterprise.context.sessionscoped; import java.io.serializable; import javax.faces.bean.managedbean; @managedbean @sessionscoped public class itemmb implements serializable { private int iditem; /** * creates new instance of itemmb */ public itemmb() { } public int getiditem() { return iditem; } public void setiditem(int iditem) { this.iditem = iditem; } public string linkitem(int id) { setiditem(id); return "item"; } }
you're mixing cdi @sessionscoped jsf 2.x @sessionscoped. noted in imports:
import javax.enterprise.context.sessionscoped; @managedbean @sessionscoped public class itemmb implements serializable { //... } this makes managed bean have default scope, in jsf 2 @requestscoped, managed bean re created on every request.
fix import to:
import javax.faces.bean.sessionscoped; if happen use jsf 2.2.x, start working cdi 1.1. use @named managed beans , use javax.faces.view.viewscoped @viewscoped.
