Monetary fields not supported in tree view

[Kevin Deldycke]

Monetary fields doesn't seems to be supported in tree views.

On a form, the following XML produce a nice "10.00 €" string:

  <record id="edit_project1" model="ir.ui.view">
    <field name="name">project.project.form1</field>
    <field name="inherit_id" ref="project.edit_project"/>
    <field name="model">project.project</field>
    <field name="arch" type="xml">
      <field name="partner_id" position="after">
        <field name="budget" widget="monetary" options='{"currency_field" : "currency_id"}'/>
        <field name="currency_id" invisible="1"/>
      </field>
    </field>
  </record>

But on a tree view, the following XML only produce the "10" string:

  <record id="project.view_project" model="ir.ui.view">
    <field name="name">project.project.tree</field>
    <field name="model">project.project</field>
    <field name="arch" type="xml">
      <tree string="Projects">
        (...)
        <field name="budget" widget="monetary" options='{"currency_field" : "currency_id"}'/>
        <field name="currency_id" invisible="1"/>
        (...)
      </tree>
    </field>
  </record>

Here I expect the tree view to behave like the form and display "10.00 €".

This behavior was produced with code from 7.0 branches, server being at Bazaar revision 4897 and web module at revision 3804.
