Extensions of Doctrine_Template_I18n incompatible with Doctrine_Import

Extending Doctrine_Template_I18n class make Doctrine_Import on YAML data with translation fails...

Why ? Just because of this line :

Doctrine_Import.php, line 135 :
if ($table->hasRelation($key) && is_array($value) && ! $table->hasTemplate('Doctrine_Template_I18n')) {

In fact, having a template named "Doctrine_Template_I18n" is not strong enough to be sure that the current object has an I18n behavior.

The bug is very simple to reproduce :

1. Get a classic I18n fixtures like :

Article:
Translation:
en:
title: Lorem Ipsum

2. Then make a simple extension of the I18n template (do not do anything else but extends the Doctrine_Template_I18n class) :

class My_Doctrine_Template_I18n extends Doctrine_Template_I18n {}

3. Load the extension, assign it to your model and try to import your fixtures again. It will not work anymore.

Thanks
