During construction of TodayPanel, it hasn't been added to the page yet so
getParent() is null. Maybe you should do the 'if(user != null) {...' stuff
in @Override ...onBeforeRender() {...}. The first time you're okay because
if (user!=null) fails and getParent() is not executed. The second time it
gets executes.
