    Getter Called Multiple Times When Using <a4j:poll>

    damendra Newbie

      Hi,


      I have been using <a4j:poll> to render a segment of a .xhtml page but the underlying bean getter method is being called multiple times, potentially causing a performance issue but also unexpected behaviour.


      The code is as following


      .xhtml:
      <a4j:region>
        <h:form>
           <a4j:poll id="poll" interval="2000" enabled="true" reRender="numberGrid" />
        </h:form>
      </a4j:region>
      
      <h:panelGrid>     
         <h:outputText id="numberGrid" value="#{number}" />
      </h:panelGrid>
      
      Bean:
      @Name("number")
      public class RandomNumber() {
      
          private int number;
      
          @Unwrap
          public getNumber(){
            Random random = new Random();
            number = random.nextInt(12);
      
            return number;
          }
      
      }
      




      Can anyone help explain and throw some light on an alternative solution?


      Regards
