I want to make invisible a field if one of those options are true, I don't know if this is possible. I try:
<field name="x_field1" string="something" attrs="{'invisible': [('x_field2','!=','value'),'|',('x_field3','=','value'),'|',('x_field4','=','value')]}"/>
And this:
<field name="x_field1" string="something" attrs="{'invisible': ['|',('x_field2','!=','value'),('x_field3','=','value'),('x_field4','=','value')]}"/>
Without success.
