[jboss-user] [EJB/JBoss] - Error during hot redeployment when trying to use dependecies

I am trying to use the depends tag in the jboss.xml to handle deployment dependecies.  
I have 3 EJBs TESTA, TESTB, and TESTC.  TESTB and TESTC have the depends tag in the jboss.xml.  If I deploy them first then they wait before trying to deploy like they are supposed to.  Once TESTA is deployed both deploy and work properly.  The problem occurs if I try and undeploy TESTA and then redeploy it.  When undeploying the following appears in the log file which makes sense.
2006-10-12 15:37:05,950 DEBUG [org.jboss.system.ServiceController] destroying dependent services for: jboss.j2ee:service=EjbModule,module=TESTA.jar dependent services are: [ObjectName: jboss.j2ee:jndiName=local/testBBean at 33317701,service=EJB
  |   State: STOPPED
  |   I Depend On:
  |     jboss.j2ee:module=TESTA.jar,service=EjbModule
  | , ObjectName: jboss.j2ee:jndiName=testCBean,service=EJB
  |   State: STOPPED
  |   I Depend On:
  |     jboss.j2ee:module=TESTA.jar,service=EjbModule
  | ]
  | 


Likewise on the redeploy a similar log comes up

  | 2006-10-12 15:37:26,903 DEBUG [org.jboss.system.ServiceController] Creating dependent components for: jboss.j2ee:service=EjbModule,module=TESTA.jar dependents are: [ObjectName: jboss.j2ee:jndiName=local/testBBean at 33317701,service=EJB
  |   State: DESTROYED
  |   I Depend On:
  |     jboss.j2ee:module=TESTA.jar,service=EjbModule
  | , ObjectName: jboss.j2ee:jndiName=testCBean,service=EJB
  |   State: DESTROYED
  |   I Depend On:
  |     jboss.j2ee:module=TESTA.jar,service=EjbModule
  | ]
  | 

this is where the problem occurs, when it tries to bring the other 2 dependants up the following errors are thrown:
TESTB:

Then TESTA finishes its deployment.

I am trying to figure out if this is the proper way to use the depends and if depends is supposed to work for redeployments.

For completeness here are the 2 jboss.xml files for the dependent beans.
