I made a form view in OpenERP7, which inherits from an existing form view.

I am trying to move some field to other position, only moving, because I need to preserve its functionality.

Easy example: let's suppose that the name of the field I want to move is field_to_move, and I want to move it just after the field called above_field. I tried the next code:

<xpath expr="/form//field[@name='field_to_move']" position="replace">
    <xpath expr="/form//field[@name='above_field']" position="after">
        <field name="field_to_move" on_change="onchange_type(field_to_move)" />
    </xpath>
</xpath>

The result is wrong, I am generating the  new field in a wrong position (the same before the changes) and the old field is still visible, so it is duplicated.
