I am working on converting traditional portal to composite portal for IE11 compatibility.
There is an existing harness which is opened and there are some buttons at the bottom. On clicking any button, the next harness is loaded. However, the pages and data of previous harness are not available at this point. Due to pages getting lost, code references to these pages fail. This results in blanking out of information/ exception on UI.

Well, if a new "Thread" is created, then this is explaining why your pages aren't accessible anymore. You will need to either work within the same "Thread" or make sure your needed pages are accessible across "Threads" for that same requestor. You can see a lot of discussion for that subject on the Community: What are some good ways to pass data between Thread Pages?
