Subject Minor problems after upgrading to 4.0
Date Wed, 12 Dec 2007 22:09:54 GMT

We've upgraded our 3.0 site to 4.0. The upgrade seemed to go ok and the new
site appears to be also running ok. But, there are a few minor problems.

The 3.0  Roller database was actually moved to a new system running FC 8,
mysql 5.0.45, and Java 1.7.

I'm not sure if these problems have already been discussed. Any help with
these would be greatly appreciated.

The register link in the frontpage template is not displayed. Though, you
can access the register form. The property the frontpage template is looking
for does seem to be set right.

The installation guide says the planet cache directory property is named
planet.aggregator.cache.dir, but the planet.properties file looks like it
uses cache.dir which is set to /var/planet/cache. Setting the former doesn't
do anything and planet is indeed storing data in /var/planet/cache.

In roller.log there are periodic exceptions like this. And the frontpage hot
tags list does not seem to be working.

Deleting a custom planet group in the Planet Adminstration form generates an
exception in roller.log

We have a planet feed subscription with a very log URL which is not
competely displayed in the subscriptions tab. But, planet does fetch data
from it anyway. Trying to delete this subscription produces an Expected
Exception page with the message "java.lang.NullPointerException". In
roller.log it says
