Directory suggestion widget in user edit layout won't show label

[a_c]

Hello community,

I overrode the default user schema to add new columns, one of them is a custom vocabulary. It saves and edits no problem, however, whenever one opens the edit dialog,** the label for the selected vocabulary is missing, only showing the numerical id of the item**, i.e:

That only happens the first time, as after editing the item, it will correctly show the label, or unless the page is reloaded. How do I solve this?

This is the xml contribution that adds the vocabulary:

<?xml version="1.0"?>
<component name="mx.gob.ssa.directory.vocabularies">
    <extension target="org.nuxeo.ecm.directory.GenericDirectory" point="directories">
        <directory name="VOC_honorifico" extends="template-xvocabulary">
            <autoincrementIdField>false</autoincrementIdField>
            <createTablePolicy>on_missing_columns</createTablePolicy>
            <table>ssa_VOC_honorifico</table>
            <dataFile>vocabularies/VOC_honorifico.csv</dataFile>
            <cacheEntryName>vocab-VOC_honorifico-cache</cacheEntryName>
            <cacheEntryWithoutReferencesName>vocab-VOC_honorifico-cache-without-references</cacheEntryWithoutReferencesName>
        </directory>
    </extension>
    <extension target="org.nuxeo.ecm.core.cache.CacheService" point="caches">
        <cache name="vocab-VOC_honorifico-cache">
            <option name="maxSize">1000</option>
            <option name="concurrencyLevel">500</option>
            <ttl>60</ttl>
        </cache>
        <cache name="vocab-VOC_honorifico-cache-without-references">
            <option name="maxSize">1000</option>
            <option name="concurrencyLevel">500</option>
            <ttl>60</ttl>
        </cache>
    </extension>
</component>

The custom vocabulary is loaded to storage using a csv file that has the fields : "id","label","obsolete","ordering".

This is the user schema extension that overrides the default user schema:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema targetNamespace="http://www.nuxeo.org/ecm/schemas/user"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:nxs="http://www.nuxeo.org/ecm/schemas/user"
           xmlns:ref="http://www.nuxeo.org/ecm/schemas/core/external-references/">

<xs:include schemaLocation="base.xsd" />

<xs:element name="username" type="xs:string" />
<xs:element name="password" type="xs:string" />
<xs:element name="firstName" type="xs:string" />
<xs:element name="lastName" type="xs:string" />
<xs:element name="company" type="xs:string" />

<!-- the new field for the custom vocabulary -->
<xs:element name="honorifico">
    <xs:simpleType>
        <xs:restriction base="xs:string" ref:resolver="directoryResolver" ref:directory="VOC_honorifico"/>
    </xs:simpleType>
</xs:element>

<xs:element name="email">
    <xs:simpleType>
        <xs:restriction base="xs:string">
            <!-- the same pattern is used in userinfo.xsd -->
            <xs:pattern value="[^@]+@[^\.]+\..+" />
        </xs:restriction>
    </xs:simpleType>
</xs:element>

<!-- inverse reference -->
<xs:element name="groups" type="nxs:stringList" />

<!-- tenant id for the user -->
<xs:element name="tenantId" type="xs:string" />

</xs:schema>

And finally, this is the widget used at the edit user layout:

<nuxeo-directory-suggestion
      role="widget"
      value="{{user.honorifico}}"
      label="Título"
      directory-name="VOC_honorifico"
      operation="Directory.SuggestEntries"
      min-chars="0">
</nuxeo-directory-suggestion>

After some research, I found out that the requests use enrichers to get additonal information. Since the only user enricher available is the userProfile, I wrote a custom enricher that finds the custom vocabulary object by id; also I had to customize the user management views to add this custom enricher to the user request (), handle the value changes and the submition of the user form.
