      Then I remembered in 1.4.3, I was trying out the new

      {redirect}

      and

      {alias} macros, and the latter one was tricky and the deletion of it wasn't complete. It left behind an empty-titled page. It didn't cause problem for the 1.4.3 and the embedded DB, but apparently it wasn't working for 1.4.4.

      Then I tried to delete that page from Oracle DB. After its deletion, I was able to access the space view and all pages. But the space view's limited to 'recently updated' view and 'alphabetically listed' view. The tree view still gave an exception as below: 
      Cause:
java.lang.NullPointerException

      Please let me know if there's other things that need to be check/deleted for that empty page (I forgot to write down the page content id though). Also please check, if possible, why {alias}

      macro caused this problem after an alias was deleted. Thanks a lot!
