[Evergreen-circ] Call Number Prefix ID's on Holds Pull List

[Morgan, Michele]

Hello Evergreeners!

We are seeing intermittent strangeness with call number prefixes when
printing the pull list.

Our print template uses this code for the prefix:
{{hold_data.volume.prefix}}

Generally it prints the prefix label as it should. Intermittently, however,
the prefix database id prints on the pull list instead of the label.

I can reproduce this issue reliably in the browser print preview (Hatch
disabled). The first time I click Print Full List, everything usually looks
fine. If I close the preview and click Print Full List again, some of the
prefixes show the ids instead of the labels. I will also occasionally see
-1 printed for call numbers that do not have prefixes.

This issue does NOT appear to be related to any of the following:

   - Browser - I've seen it in both Chrome and Firefox
   - Hatch - I've seen it with and without Hatch enabled
   - Server - I've seen it on several servers running different releases,
   including our production and training servers, a test vm, and the community
   server demo.evergreencatalog.com

I just previewed a pull list for BR1 on demo.evergreencatalog.com, and two
of the call numbers printed as:

-1 FIC 222
-1 MR 248

The reporting library indicated this started about two months ago. Has
anyone else seen this?

Any ideas?

Michele
