What I'm trying to do is to populate a dropdownlist from database (num_bc). I added the schema bc, I registered it, and I created a new Directory bc_directory. All is good I can see the values on the Dropdown list but once I click on it I can't select its value.

Here's the log content:

[org.nuxeo.ecm.platform.ui.select2.common.Select2Common] Unable to find field num_bc in directory schema bc. Trying to fallback on default one.

Here's my Code: Schema:

<?xml version="1.0"?>

Schema registrations:

<extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
    <schema name="bc" src="schemas/bc.xsd" />
</extension>

I searched for the error generated, I found that I have to delete the prefix on schema I did not working though.

<extension target="org.nuxeo.ecm.directory.sql.SQLDirectoryFactory"
    point="directories">
    <directory name="bc_directory">
