jsf - Two h:commandButton in the same h:form: one works, the other doesn't -

i have .xhtml piece of code:

<h:inputtext value="#{boardmbean.logintoadd}"/> <h:commandbutton action="#{boardmbean.adduser}" immediate="true" process="@this" value="adicionar"/>  (...)  <h:commandbutton action="#{boardmbean.edit}" value="salvar" class="btn btn-large"/>                  

the second h:commandbutton works fine, i.e., submits form correctly. in other hand, first, instead of calling adduser() method boardmbean, refresh page , nothing happens.

i'm using jsf 2.2 , application running on jetty. managed bean is:

import java.io.serializable;  import javax.faces.bean.managedbean; import javax.faces.bean.requestscoped; import javax.faces.bean.viewscoped;  @managedbean(name="boardmbean") @requestscoped public class boardmbean extends generalcontroller<board> implements serializable {      /** login of new user of board. */     private string logintoadd;      /** selected role add user. */     private roleboard role;      /**      * constructor.      * */     public boardmbean() {         obj = new board();     }      /**      * prepare board update.      *       * @return sends same edit page.      * */     public string loadboard() {(doesn't matter).}      /**      * called edit/create board use case.      *       * @return sends list of tables.      * */     public string edit() {(works fine.)}      /**      * add user board.      *       * @return same page.      * */     public string adduser() {          if (logintoadd != null && !logintoadd.equals("")) {             userdao udao = new userdao();              // retrieve user login             user u = udao.getuserbylogin(logintoadd);              // if exists             // todo check if exists in board             if (u != null) {                 // build relation                 boarduser boarduser = new boarduser(u, obj);                 // role                 boarduser.setrole(role);                  userboarddao ubdao = new userboarddao();                 ubdao.create(boarduser);                  obj.getusers().add(boarduser);                  boarddao bdao = new boarddao();                  // commit change                 bdao.update(obj);              } else {                 //todo user not found             }         }         return null;     }      public roleboard getrole() {         return role;     }      public void setrole(roleboard role) {         this.role = role;     }      public string getlogintoadd() {         return logintoadd;     }      public void setlogintoadd(string logintoadd) {         this.logintoadd = logintoadd;     }  } 

since i'm using jetty, there exist well-known problem @managedbean annotation, makes me use faces-config.xml (just now) indicate managed beans. how looks like:

<?xml version="1.0" encoding="utf-8"?> <faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"     version="2.2">      <managed-bean>         <managed-bean-name>usermbean</managed-bean-name>         <managed-bean-class>com.vinivitor.trackit.control.usermbean</managed-bean-class>         <managed-bean-scope>request</managed-bean-scope>     </managed-bean>      <managed-bean>         <managed-bean-name>boardmbean</managed-bean-name>         <managed-bean-class>com.vinivitor.trackit.control.boardmbean</managed-bean-class>         <managed-bean-scope>request</managed-bean-scope>     </managed-bean>  </faces-config> 

does know how make first h:commandbutton work expected?

thanks in advance.
