Computed field calc when user lang different from default lang

[lucaslaurent04]

If the user's lang differs from the default lang, there is a bug when saving a computed field value in the database table.

First the value is loaded and stored in cache in fr lang (user's lang)

equal/lib/equal/orm/ObjectManager.class.php

Line 591 in 8f5443c

$om->cache[$table_name][$oid][$lang][$field] = $value;

Then the orm try to store the cached value in en lang (default lang)

equal/lib/equal/orm/ObjectManager.class.php

Line 865 in 8f5443c

$value = (isset($om->cache[$table_name][$oid][$lang][$field]))?$om->cache[$table_name][$oid][$lang][$field]:null;

The value stored is NULL because no value is found for en
