Possible Cyclic Reference

Question

I am getting the possible cyclic reference error in my JSF 1.0 application. However, I am not sure if this is an actual cyclic reference or just a bug, which was fixed in Mojarra. Can someone please look at my faces-config and tell me if this is an actual cycle:
     <managed-bean>
          <description>Internal Backing Bean</description>
          <managed-bean-name>internalBB</managed-bean-name>
          <managed-bean-class>com.app.InternalBB</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
     <managed-bean>
          <description>External Backing Bean</description>
          <managed-bean-name>externalBB</managed-bean-name>
          <managed-bean-class>com.app.ExternalBB</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
     <managed-bean>
          <description>Internal Archive Backing Bean</description>
          <managed-bean-name>archiveIntBB</managed-bean-name>
          <managed-bean-class>com.app.InternalArchiveBB</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
          <managed-property>   
               <property-name>internalId</property-name>               
               <value>#{internalBB.selectedId}</value>
          </managed-property>
     </managed-bean>
     <managed-bean>
          <description>External Archive Backing Bean</description>
          <managed-bean-name>archiveExtBB</managed-bean-name>
          <managed-bean-class>com.app.ExternalArchiveBB</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
          <managed-property>   
               <property-name>externalId</property-name>               
               <value>#{externalBB.selectedId}</value>
          </managed-property>
     </managed-bean>

Answer 1

I thought so, too.
It turns out that in the constructor of one of the archive managed beans, a NullPointerException was being thrown during a method. Not sure why it manifests itself out as a cyclic reference error, but there you have it. I probably should've just dug deeper in the stack right off the bat, but the cyclic reference error sent me on a wild goose chase.
Thanks again.
