1.2, i18n, multilingual and translate behavior  
Note
First, you need to set a
Configure::write('Config.languages', array('la1', 'la2'));

to indicate what languages your application supports.

Add 'Translate' and 'Multilingual' to the array of Behaviors of your model.

When you want to get multilingual versions of the data, previously you must call

model->getLocales();

to activate the multilingual find.

The translated results comes as an array

[field][la1]
[field][la2]
