Comment 4 for bug 2045989

Upon testing this, I have a question about the desired behavior.

Consider this workflow:

[1] Create a template that sets the circulation modifier and the classification.
[2] Create a new item, and apply the template.
[3] Realize that you wanted to add more to the template, so you set the call number prefix and the age protection fields.
[4] Save the template, then export it.
[5] Here are the results:

- circ_lib and age_protect are set
- _only_ the prefix is set, not the classificaiton

Should it not retain the values of any (unchanged) call number fields taken from an original template when saving updates back to it?
