Hi,
I've started to play around with JBoss Portal to see how it can be used in
different systems as the presentation layer for us in J2EE systems (and 2.2
seems to be nice in the near future too).
While playing around I installed the forums and it seems to work fine to add
categories and forums, post new topics and even preview the topics before the
actual submit. But when trying to open a topic for reading I get a null pointer
exception (see below). Regardless of user ("admin" or "user" used as the
creator and/or viewer.
JBoss Portal: 2.0.1RC3
JBoss Portal Forums: 2.0.1RC3
DB: MySQL 5.0.16
DB connector: mysql-connector-java-3.1.11
OS: Win XP sp2
Additional information:
The hibernate mapping was not working and confirmed in the forum here in posts
I found (mysql 5 incompatibility with booleans) so I manually changed the types
of those columns in both the jbp-tables (2 columns) and jbp_forums tables (1
column). I then manually added the information in the portal installation
(setup.txt script). Didn't seem to be needed for the forums, as all it does is
create a category with 2 forums and I could do that in the gui anyway.
Also changed to use PortalDS_2_0_0 in the forums installation as that was used
in the portal config files for 2.0.1rc3.
No other problems found in the portal+forums setup while clicking around and
trying things.
Stack trace when clicking on a topic in the forums:
