FACTS 


STEPS

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

 

  1. Deploy a producer application with 2 portlets displaying data in an af:table. 
  2. Add a portlet to a page in a portal. 
  3. View the page. 
  4. Navigate away and get back to see the page. 
  5. Keep navigating and look at the page with the portlets.
    The portlets will either be blank or get "Remote Portlet" error. 
  6. Add one more portlet to the page. 
  7. Navigate away and get back to see the page. 
  8. Keep navigating and look at the page with the portlets.
    The portlets will either be blank or get "Remote Portlet" error more consistently.
