STEPS

The issue can be reproduced at will with the following steps: 

1. Navigate to the page with the portlet.
   
   
2. Interact with the Portlet.
   Here you can see all works fine.
   
   
3. Leave the page open for some time (e.g. 5 minutes).
   
   
4. Attempt to interact with the portlet again.
   Here you will get the ADF_FACES-60101 error.
