Symptoms

When interacting with a Custom Task Flow in WebCenter Portal 12.2.1.3, a pop-up is shown with the following:

ADF_FACES-30200:For more information, please see the server's error log for an entry beginning with: The UIViewRoot is null. Fatal exception during PhaseId: RESTORE_VIEW 1

No action takes place in the custom task flow.
