UIViewRoot is null on page load after migrating from 12.1.3 to 12.2.1.4

2786120Sep 21 2020

Hi Guys,

Can you Help me..

Jdeveloper Version: 12.2.1.4

I'am migrating ADF application from JDev 11.1.2.1 to 12.2.1.4.Authentication is implemented with PhaseListener where in afterPhase method I redirect a user from any other page to Login.jsf page if not already authenticated. In afterPhase method I check the current page name to which a user wants to navigate with: public void afterPhase(PhaseEvent event) { ... FacesContext context = event.getFacesContext(); String viewId = context.getViewRoot().getViewId(); ... if viewId is in the list of "protected pages " then goto Login.jsf page } In JDev 11.1.2.1 where it was originaly developed it works fine, after migrating the application to 11.1.2.4 it works fine, after migrating the application to 12.1.3.0 it works still fine, but after migrating the application to 12.2.1.2 I get in browswer: 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 The reason is, that in 12.2.1.4 context.getViewRoot().getViewId() evaluates to null.

Completed log:
