Re: Rss feed issue
Not sure what to tell you. I usually get null pointer exceptions when
the constructor for a custom java class fails. My first thought would
be that something changed in the feed definition XML and maybe it's
throwing off the selected items. Clearly something changed between
the time it worked and the time it stopped working. If you didn't
change any code then the best guess might be the feed itself.
Is there any way to investigate that?

Re: Rss feed issue
Another thought might be that the descriptions (titles, too) within the feed do not appear to be in a CDATA block. If there are invalid characters in there then that might affect how the XML is processed. Just a thought. ~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:238553 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
RE: Rss feed issue
I will try, and will clear the template cache, etc etc. There are two
feeds, and both are broke, so it must be on my end.
