Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Sachin Ghai 2012-01-02 08:32:37 UTC 
Description of problem:
I registered a system using rhsm and was trying to view 'package groups' under the system packages. I was searching for "Development Tools". I typed the "Development Tools" in the search box and clicked on 'Load More' button. None of the package groups were listed on UI. And got a long traceback in the production.log with error on UI:

undefined method `each' for nil:NilClass

Version-Release number of selected component (if applicable):
installed katello:

[root@dhcp201-197 ~]# rpm -qa | grep katello

[root@dhcp201-197 ~]# 


installed rhsm version:
=================

[root@dhcp201-139 ~]# rpm -qa | grep subscription-manager
subscription-manager-0.98.3-1.el6.x86_64
[root@dhcp201-139 ~]# rpm -qa | grep katello-agent
katello-agent-0.13-1.el6.noarch
[root@dhcp201-139 ~]# 


How reproducible:
always

Steps to Reproduce:
1. register a system using rhsm
2. Install katello-agent and configure it on client node
3. Go to "Systems ==> select the registered system ==> packages ( in right pane) 
4. now select "package group" and search for "Development Tools"
5. click on "Load more"
  
Actual results:
Package groups are not listed on UI and getting "undefined method `each' for nil:NilClass"

Expected results:
Package groups  should be listed on UI without any error.

The issue was related to how the offset for the current number of loaded packages was set for loading more packages as the number of total loaded approached the overall total number.  This was not a direct result of searching or using the Package group feature.
Comment 3 Mike McCune 2012-01-26 19:07:34 UTC 
mass ON_QA move
Comment 5 Sachin Ghai 2012-02-13 12:38:57 UTC 
Verified with following build:

katello-glue-pulp-0.1.226-1.el6.noarch
pulp-0.0.265-1.el6.noarch
katello-0.1.226-1.el6.noarch


The reported issue is no longer reproducible. I guess the backtrace was due to 'Load n more' issue (#767479). That has been resolved now.
Comment 7 Mike McCune 2013-08-16 18:14:18 UTC 
getting rid of 6.0.0 version since that doesn't exist
