Auto install bean session?

I have a bean session

<managed-bean>
  <managed-bean-name>vdcAddBean</managed-bean-name>
  <managed-bean-class>com.cloud.appsportfolio.jsf.vdc.beans.VDCAddBean</managed-bean-class>
  <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

Now I insert this bean into the request:

<managed-bean>
      <managed-bean-name>providerSelectionBean</managed-bean-name>
      <managed-bean-class>com.cloud.appsportfolio.jsf.sourcing.ProviderSelectionBean</managed-bean-class>
      <managed-bean-scope>request</managed-bean-scope>
      <managed-property>
        <property-name>vdcAddBean</property-name>
        <property-class>com.cloud.appsportfolio.jsf.vdc.beans.VDCAddBean</property-class>
        <value>#{sessionScope.vdcAddBean}</value> 
      </managed-property>
</managed-bean>

Well, when I access vdcAddBean in providerSelectionBeanjava code, I get NPE because it vdcAddBeanis not yet initialized. If I go first in my menu, on the page with vdcAddBeanin the background, and return to providerSelectionBean, everything works fine, because it seems to be vdcAddBeanalready initialized.

The question is: how can I get vdcAddBean to initialize (if it is zero) when accessing the providerSelectionBeanbean?

Thank.

Replace

<value>#{sessionScope.vdcAddBean}</value>

by

<value>#{vdcAddBean}</value>

to force JSF to auto-create a bean.

JSF beans ExternalContext, , : getSessionMap.

- bean -name, , , null, , bean sessionMap?
