Unable to view 'package groups' from system packages and getting "undefined method `each' for nil:NilClass" none

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.

Unable to view 'package groups' from system packages and getting "undefined method `each' for nil:NilClass"

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
