Do you mean that you cannot browse by item? If so the following may be of use to you: 2009/7/2 Halliday, James Leonard <[email protected]> > > > I have a similar problem, but no newly defined field: I can't browse > > by author or subject, as I get a java.lang.NullPointerException very > > similar (or so it seems to me) to Lyn's error.

I copied those lines (536-566) to a similar spot in the preceding browseByItem method (line 366) and commented them out in the browseByValue method.
