    Boolean values in backing bean are (unexpectedly) initialized after ajax call

    Matthias Gerhards Newbie

      Hi All,

      I am new to this forum and hope that this is the right place for my question/issue. I am posting this her,e because I am not shure if it is an issue or not.


      Situation:

      I am migrating my rich faces 4.3.6 application from glassfish to tomcat Apache Tomcat/7.0.53. I have an interesting
      issue with the a4j:ajax feature and the h:selectOneMenu.

       

      Problem:

      If an ajax event is processed the jsf/rich faces seems to initialize every boolean attribute of my backing
      beans with an initial value = false. Only if excecute and render are @form. Has anybody experienced something like that before?

       

      The user never clicked one the component and the value should still be null.

      I used Boolean and not the primitive type boolean in my backing bean.

       

      My example facelet looks like this:
      -----------------------------------------------------------------
      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

            xmlns:h="http://java.sun.com/jsf/html"
            xmlns:f="http://java.sun.com/jsf/core"
            xmlns:a4j="http://richfaces.org/a4j"
            xmlns:rich="http://richfaces.org/rich">

      <h:head>
         <title><ui:insert name="title">Tomcat test init issue</ui:insert></title>
      </h:head>
      <h:body>
      <h:form id="avaro">
      <h:selectOneRadio id="firstSelect" 
             value="#{myTestBean.firstBooleanValue}">
        <f:converter converterId="javax.faces.Boolean"/>       
        <f:selectItem itemLabel="True" itemValue="true" />        
        <f:selectItem itemLabel="False" itemValue="false" />
        <a4j:ajax event="click"
            render="@form"
            execute = "@form"
        />
      </h:selectOneRadio>

      <h:selectOneRadio id="secondSelect" 
             value="#{myTestBean.secondBooleanValue}">
        <f:converter converterId="javax.faces.Boolean"/>       
        <f:selectItem itemLabel="True" itemValue="true" />        
        <f:selectItem itemLabel="False" itemValue="false" />
      </h:selectOneRadio>
      </h:form>
      </h:body>
      </html>

       

      My Backing bean looks like this:
      --------------------------------------------------------

      package de.dvka.avaro.frontend.jsf.beans;

      import java.io.Serializable;
      import javax.enterprise.context.SessionScoped;
      import javax.inject.Named;


      @Named ("myTestBean")
      @SessionScoped
      public class MyTestBean implements Serializable{

      private static final long serialVersionUID = 3475839275576533364L;
      Boolean firstBooleanValue;
      Boolean secondBooleanValue;

      public Boolean getFirstBooleanValue() {
        return firstBooleanValue;
      }
      public void setFirstBooleanValue(Boolean firstBooleanValue) {
        this.firstBooleanValue = firstBooleanValue;
      }
      public Boolean getSecondBooleanValue() {
        return secondBooleanValue;
      }
      public void setSecondBooleanValue(Boolean secondBooleanValue) {
        this.secondBooleanValue = secondBooleanValue;
      }
      }
