MARC editor authority browse context menu not rendered if one the authority records listed lacks an 003 field

[Galen Charlton]

For bib fields meant to be controlled by authority records, right-clicking on one of their subfields in the MARC editor is supposed to bring up a context menu displaying relevant authority records. However, if any of the authority records that would be retrieved does not have an 003 field, the authority popup menu is not displayed; instead the default context menu is displayed.

This stems from a line in marcedit.js that retrieves the contents of the 003 field but throws an uncaught exception if that control field is not present.

A similar problem occurs if one of the authority records lacks a 901$c.

Also affects master.

A fix is available at the tip of the user/gmcharlt/lp1235474_fix_auth_ctx_menu_crash branch in the working/Evergreen repository:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/gmcharlt/lp1235474_fix_auth_ctx_menu_crash

The patch deals with the case where an authority record lacks an 003 field, as there is nothing that strictly enforces that all authority records have an 003 field. In contrast, triggers ensure that they will always have a 901$c.

Good fun setting up this one for testing:

UPDATE config.global_flag SET enabled = FALSE WHERE name = 'cat.maintain_control_numbers';
UPDATE authority.record_entry SET marc = replace(marc, '003', '004') WHERE id = 9;

Then search the bib records for "Petrov", open the bib record in the MARC editor, and right click on the "Petrov" field... there we go!

Thanks for the fix, Galen; much appreciated, and pushed to master, rel_2_5, and rel_2_4.
