[rt-users] dealing with aftermath of upgrade from 4.0 to 4.2 : "no value sent for required parameter 'Object'" error message

I'm in the process of upgrading an RT4 installation to the latest release (and after that: to do some performance upgrading).

If I upgrade RT4.0.22 to RT4.2.9 the installation starts suffering from multiple errors. The result of the upgrade is "clickable" and most of RT seems to be working. I'm hoping that some pointers from people that are more savvy to RT4's internals will help me resolve the issues I am facing.

The upgrade has been performed on a cloned VM (ubuntu 12). There - unfortunately - were/are no scary error messages encountered during the upgrade.

When we try to verify the upgrade it quickly becomes apparent that :

Clicking on "Display" ( the generated URL being : https://tickets.quanza.net/Ticket/Display.html?id=XXX where XXX is the tickets ID) for an individual ticket results in this entry in the logfile:

[2334] [Wed Dec 24 15:05:39 2014] [warning]: Use of uninitialized value in concatenation (.) or string at/ //opt/rt4/sbin/../lib/RT/Interface/Web.pm line 1884. (/opt/rt4/sbin/../lib/RT/Interface/Web.pm:1883) 
[2334] [Wed Dec 24 15:05:39 2014] [warning]: Use of uninitialized value in concatenation (.) or string at/ //opt/rt4/sbin/../lib/RT/Interface/Web.pm line 1884. (/opt/rt4/sbin/../lib/RT/Interface/Web.pm:1883)
[2334] [Wed Dec 24 15:05:40 2014] [error]: no value sent for required parameter 'Object'

I think it might have something to do with this comment:

MakeClicky handlers added via a callback are now passed an "object" key in the parameter hash instead of "ticket". The object may be any RT::Record subclass.

on https://www.bestpractical.com/docs/rt/4.2/UPGRADING-4.2.html , but I'm really kind of in the dark here.

The steps performed (on the clone of my current RT4 setup) were:


wget https://download.bestpractical.com/pub/rt/release/rt-4.2.9.tar.gz
tar -xvf rt-4.2.9.tar.gz
cd rt-4.2.9

service apache2 stop

make testdeps
make fixdeps

altering Makefile to fit our user-setup:

WEB_USER = www-data

make upgrade
make upgrade-database

rm -fr /opt/rt4/var/mason_data/obj
sed -i 's/LogToScreen/LogToSTDERR/g' /opt/rt4/etc/RT_SiteConfig.pm
chown www-data:rt /opt/rt4/var/data/gpg

service apache2 start


I'm apologizing for asking the obvious if I really should have been heeding instructions that are available more closely (please feel free to point that out very blatantly :P).

Any insights / thoughts on what might be going wrong here would be greatly appreciated (if any more information is required: i'm happy to provide it)!

Kind regards,
