Unable to translate extended plugin fields

[mskraban]

I'm trying use translate plugin with my extended plugin fields. I tried to use translatable in model where it usually works when it's not extended and in controller (Plugin.php).

Model.php

    public $implement = ['@RainLab.Translate.Behaviors.TranslatableModel'];
    public $translatable = ['specs','featured_specs','features', 'fullspecs', 'optional_equipment', 'condition'];

Plugin.php

        ProductModel::extend(function($model) {
            $model->addJsonable([
                'featured_specs',
                'features',
                'specs',
            ]);

            $model->implement[] = 'RainLab.Translate.Behaviors.TranslatableModel';
            $model->translatable = ['specs','featured_specs','features', 'fullspecs', 'optional_equipment', 'condition'];

        });

Hi @mskraban,

This looks good and should work. If you are having trouble, try to reproduce any problems using the test plugin so we can also test it.

One thing to check, if the translatable property is not available in the model, you may need to dynamically add it with code like this

ProductModel::extend(function($model) {
    if (!$model->propertyExists('translatable')) {
        $model->addDynamicProperty('translatable', []);
    }
    if (!$model->isClassExtendedWith('RainLab\Translate\Behaviors\TranslatableModel')) {
        $model->extendClassWith('RainLab\Translate\Behaviors\TranslatableModel');
    }
    $model->translatable = array_merge($model->translatable, ['title', 'description', 'meta_title', 'meta_description']);
});

I hope this helps.
