on_change field not valorized with xpath

[Matteo Boscolo]

I implemented e little modification at the contract to allows creation of sub contract and the related name.
For this I implemented the on_change event on the parent_id filed.

this is the xml xpath that change the interface ..
<xpath expr="//field[@name='code']" position="after">
    <field name="parent_id" on_change="on_change_parent_id(partner_id,name,parent_id)"/>
</xpath>
the parent id field is not valorized inside the python code ..

I attached the module that implement the code above.

Matteo

I found the solution at the problem,
There was already a view that define the parent_id,
I overwrite the field with replace and all works well ...

<xpath expr="//field[@name='code']" position="replace">
    <field name="parent_id" on_change="on_change_parent_id(partner_id,name,parent_id)"/>
</xpath>
