Rendered Property

[SANTINI, Rafael]

Hi,

In the following code, the last two components are rendered on the condition 
"#{bean.campo1 != null}". When the bean.campo1 is different that null, they 
are displayed. But, when the last button is clicked, the testar method is 
not invoked. What I'm missing?

<h:messages/>
<h:form>
 <h:inputText value="#{bean.campo1}"/>
 <h:commandButton value="OK"/>
 <h:inputText value="#{bean.campo2}" rendered="#{bean.campo1 != null}"/>
 <h:commandButton value="Testar" action="#{bean.testar}" 
rendered="#{bean.campo1 != null}"/>
</h:form>

public class Bean {

   private String campo1;

   private String campo2;

   public String getCampo1() {
       return campo1;
   }

   public void setCampo1(String campo1) {
       this.campo1 = campo1;
   }

   public String getCampo2() {
       return campo2;
   }

   public void setCampo2(String campo2) {
       this.campo2 = campo2;
   }

   public void testar() {
       campo2 += "_OK";
   }

}

Thanks,

Rafael Santini
