Lists and vocabularies: Identifier missing when creating a new concept
I'm using Providence (and Pawtucket) v.1.7.8 on a Linux server and DublinCore v14.
When creating a new concept through Lists & vocabularies, when I click Save, the identifier is not set.
Here are the steps I am doing:
1. MANAGE > Lists & vocabularies
2. Add new concept under existing category (either by directly creating under desired category or by creating a sibling to an existing concept under desired category)
3. Fill in Preferred labels and add custom identifier
4. Click Save
As you an see, the identifier is not set and, hence, is not displayed.
I have checked the database and the idno field in table ca_list_items for created entries is empty.
I checked the logs in /app/logs but no error messages are displayed.
Could You please advise on what might be happening or what other checks could I perform?
Thanks in advance,
