Schema lib389 object is not keeping custom schema data upon editing

[droideck]

Description of problem:
While editing a custom schema attribute, lib389 and Web UI is not keeping some defined data:

1. if the "Description" is updated, the "OID" is reverted to "<ATTRIBUTE_NAME>-oid"

2. if the "OID" is updated, then the "Description" field shows "No description".

How reproducible:
Always.

Steps to Reproduce:

1. Create a custom attribute ( Schema tab / Attributes tab / "Add Attribute" button )
2. Edit the newly created attribute and change either the description or the OID
3. Save
4. Only the updated field is kept. The non-updated field is reverted to its default value.

Actual results:
Custom datum is lost.

Expected results:
Keep all custom values.

Additional info:

1. A workaround is to update both fields at the same time:

Set the two fields ( Description and OID ) to dummy values and save.
Edit the attribute again
Set the two fields to the correct values and save
2) JS Console:
