[Rssview-developers] Can't load old prefs?

Hi,

I updated from CVS a few minutes ago and now I find that I can't reload my
old preferences file. That's really, really painful since we store all the
channel configurations in there. Maybe this is related to the fact that the
rssviewdb.* files got renamed to .rssviewdb.*?

I should have renamed mine, I guess, but I deleted them. Pity.

Can you wrap exceptions, every time you see one, please? I don't want 
the user see any of such problems. Solutions might be: error output
on console or (preferred) a JOptionPane. Whatever appropriate, but
not an exception.

Please "fix" such things as soon as possible. It's only 5mins job,
but it attracts more users when they have a feeling of a seemingly 
clean application.

If you updated your ArticleDatabase class in de.cinek.rssview.io package 
and renamed the rssviewdb files to .rssviewdb everything should work 
fine. This Exception occurs just if the hierarchie of the TreeNodes does 
not match the Channels in the Database. This Exception will never ever 
occur under normal circumstances (no renaming, deleting). If the 
Exception gets thrown even after renaming and update the only solution I 
have is to delete ALL settingsfiles of rssview. I consider implementing 
a "health check" to make the datamodel more stable so that this 
exception will not occur anymore.
