Hello,
I'm using castor JDO to load a simple set of objects from a database using a
query, to generate a list view in a web iterface to the database. The list
used to work nicely, but after I added more objects to the database, I kept
getting NullPointerExceptions inside castor. The funny thing is, they don't
occur ALWAYS, but they seem to occur more often when there are more objects
to be loaded from the ResultSet generated from the query.
Now there are about 15 objects to be loaded from the ResultSet through a
simple QueryResults iterator, and somewhere in the middle it generated the
NullPointerException while calling QueryResults.hasMore(). (see end of mail)
Has anyone seen this before, or know how to solve this? Any help will be
greatly appreciated.
Kind regards,
Jan Ypma
