Description of problem:
Under the Content -> Errata page, if you choose some errata and click the 'Apply' button, this will take you to a screen to choose hosts to apply the errata to.

On this screen, there are some columns of information that are blank for all hosts, that should /never/ be blank. (Environment and Content View)

Version-Release number of selected component (if applicable): 6.2.6

How reproducible: 100%

Steps to Reproduce:
1. Click Content -> Errata
2. Check some errata, click apply.
3. Observe Environment / Content View columns for content hosts.

Actual results:
No content in these columns for any hosts.

Expected results:
Should list current Environment / Content View.

Additional info:
This may be causing an additional issue with the Dropdown box on this page to select hosts only in a particular 'lifecycle environment' not taking effect / working at all. I will file a separate BZ for this.
