How to get a parameter from each request in a session scope BackingBean

Question

While calling my JSF page, I pass an id as parameter in the URL, and in the Backing bean I retrieve it from the request.
On each request I need to get the id and populate the page accordingly.
But I am forced to create my Backing Bean in session scope b'cos otherwise ValueChangeListener method does not work properly.
So where and how do I get the id on each request?
Pls. help

What you can do is create it in the request scope like this:
<managed-bean>
      <managed-bean-name>personBean</managed-bean-name>
      <managed-bean-class>
        com.PersonBean
      </managed-bean-class>
      <managed-bean-scope>request</managed-bean-scope>
       <managed-property>
             <property-name>id</property-name>
             <property-class>java.lang.Long</property-class>
          <value>#{param.id}</value>
      </managed-property>
</managed-bean>And then in the page use a hidden field to set the id in case of a postback (validation error):
<h:inputHidden id="id" value="#{personBean.id}"/>Does that help you?
