Description Chris Pelland 2012-06-01 18:13:12 UTC

+++ This bug was initially created as a clone of Bug #807291 +++

Description of problem:

While creating an activation key I added a bonus pool to it (an available subscription created by consumption of a physical subscription). I then removed the system with the physical subscription, thus effectively eliminating the bonus pool. Viewing the activation key and selecting "Applied Subscriptions" tab throws error:

undefined method `productName' for nil:NilClass

Hi Tom, what's the customer impact of this issue?  Is this a common scenario?  Does the presence of the 'nil:NilClass' failure introduce any non-recoverable issues?

--- Additional comment from mmccune on 2012-04-18 11:43:05 EDT ---

moving to 1.0.z

--- Additional comment from tomckay on 2012-04-30 12:48:47 EDT ---

Hopefully not common. 1.0.z would be good

Subscription pools are checked for validity before the activation key can be accessed.

Comment 5 Kedar Bidarkar 2012-06-21 09:46:33 UTC

No errors seen with the latest puddle 2012-06-18.1

I would list out the steps followed here.

a) import a subscription manifest
b) synced rhel6.2 content
c) registerd and subscribed a system 
d) which consumed a physical type subscription and created a bonus pool which had 4 virtual type subscriptions.
e) Added this virtual type subscription to the activation key via, Available subscriptions
f) Moved to Applied Subscriptions tab to check for the presence of the virtual subscriptions
g) Removed the physical system , which actually created the bonus pool
h) Moved to the Applied Subscription under Activation keys section, to check for erros.

FOUND NO ERRORS.

It just displays : "There are no more subscriptions available."
