Question

I want to register logs when i update my entity with gdmo-loggable, the table exists but no one register.

Here's my current code

# config.yaml

      orm:
        auto_generate_proxy_classes: "%kernel.debug%"
        naming_strategy: doctrine.orm.naming_strategy.underscore

        filters:
            softdeleteable:
                class: Gedmo\SoftDeleteable\Filter\SoftDeleteableFilter
                enabled: true
        mappings:
            gedmo_translatable:
                type: annotation

                dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Translatable/Entity"
                is_bundle: false

            gedmo_loggable:

                dir: "%kernel.root_dir%/../vendor/gedmo/doctrine-extensions/lib/Gedmo/Loggable/Entity"
                alias: GedmoLoggable # (optional) it will default to the name set for the mapping
                is_bundle: false

            translatable: true
            loggable: true
    default_locale: fr_FR
    translation_fallback: true

#service.yaml

After following instructions from doc and searching on the web i have a problem with gedmo loggable from doctrine extension in my symfony project (3.3). There is no log data in table ext_log_entries when i update my entity. It's possible that my event priority catching nothing because it's priority is equal at 0 ? If someone have an idea, it would be helpful.
