I have a very simple xhtml file where a panelGroup containing a commandButton is added to the page on clicking toggle button but this dynamically added commandButton fails to execute its actionlistener on being clicked.

Complete code below:

<?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">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html" 
      xmlns:p="http://primefaces.org/ui">

    <h:head>
    </h:head>
    <h:body>
        <h:panelGroup id="checkDyna">
            <h:panelGroup rendered="#{listRetriever.booleanStatus}" >
                <h:form>            
                    <p:commandButton value="check" process="@all" actionListener="#{listRetriever.xx()}"/>
                </h:form>
            </h:panelGroup>
        </h:panelGroup>
        <h:form>
            <p:commandButton value="Toggle" actionListener="#{listRetriever.toggleBooleanStatus()}" update=":checkDyna"/>
        </h:form>

    </h:body>
</html>

Bean

@ManagedBean(name = "listRetriever")
@RequestScoped
public class ListRetriever implements Serializable {

    private boolean booleanStatus;        

    public void toggleBooleanStatus(){
        if (!booleanStatus)
            booleanStatus=true;
    }

    public void xx(){
        System.out.println("Invoked***");
    }

    public boolean isBooleanStatus() {
        return booleanStatus;
    }

    public void setBooleanStatus(boolean booleanStatus) {
        this.booleanStatus = booleanStatus;
    }

}

On removing rendered="#{listRetriever.booleanStatus}" actionlistener is successfully invoked.

On making the bean ViewScoped too the problem is eliminated but I dont want to make it wider than RequestScoped.

    I had this p:commandButton within a conditionally rendered panel whose conditional expression for rendering was evaluating to false while I was trying to execute the actionlistener. This was the cause of actionlistener not getting executed.
