Dear all,
I have introduced entities into our DSpace 8.2 installation. While I have
modified some relationships, all entities remain standard and mostly
functional. However, I am experiencing an issue with unselecting entities
in the submission form.
I defined a <relation-field> that is non-repeatable, as shown below:
<relation-field>
<relationship-type>isPublicationOfIssue</relationship-type>
<search-configuration>publication</search-configuration>
<repeatable>false</repeatable>
<label>Publication</label>
<hint></hint>
<linked-metadata-field>
<dc-schema>journalIssue</dc-schema>
<dc-element>relation</dc-element>
<dc-qualifier>publication</dc-qualifier>
<input-type>onebox</input-type>
</linked-metadata-field>
<externalsources></externalsources>
</relation-field>
The problem is that the UI does not update immediately after deleting or
unselecting the entity, it only refreshes after performing another action
(like adding an entity in another relation-field). Additionally, I
encounter the following error, which appears to be related to the system
expecting a repeatable field. When I set the field as repeatable,
unselecting works fine; the issue only occurs with non-repeatable fields.
ERROR TypeError: Cannot read properties of null (reading 'context')

Has anyone experienced similar issues or found a solution?
Thank you and best regards,
