I'm testing XE 2.6 with XEM. My plugins/applications are
(corresponding .jar files are at WEB-INF\lib)
Our Environment is Jboss 4.2.1 web server and Oracle 10g database.
There is a problem with the Activity Stream at the homepages of the farm members.
The "Activity Stream" keeps empty and there are some identical lines within the jboss console log:
15:50:59,267 ERROR [DefaultVelocityEngine] Left side ($events.size()) of '>' operation has null value at unknown namespace[line 648, column 21]
After disabling the "Right column" of the Dashboard page the error does not appeare.
