[tryton] Reference field domain on a xml file

[jmartin]

Hi,

I've wondering whether is possible to set a domain in an action defined on 
the xml file for a reference field. I've tried

<field name="domain">[('origin','=', 'account.statement,%s' % 
Eval('active_id'))]</field>

But it does not work. Any idea will be welcome.

Thanks,
