Description of problem:
The link to the details of the last configuration file comparison for a system returns a 404 error Spacewalk 2.2.  This is likely due to the rewrite of some more of the Perl pages to Java since the link points to event.pxt, which is no longer present.

Version-Release number of selected component (if applicable):
spacewalk-html-2.2.33-1.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. add a system
2. assign config channel
3. make a change to the system
4. perform a comparison
5. try to view the diff from the 'Configuration' -> 'Overview' page of the system by clicking the 'View Details' link

Actual results:
404

Expected results:
differences shown as in 2.1
