Hello,

Im trying to install a new module using the access right's dropdown style.

For using the dropdown style, I configure the security.xml like this:

<odoo>

    <record model="ir.module.category" id="mymodel_category">

        <field name="name">My Model</field>

        <field name="description">Test my Module</field>

        <field name="sequence">81</field>

    </record>

    <record id="group_mymodel_manager" model="res.groups">

        <field name="name">Manager</field>

        <field name="category_id" ref="mymodel_category"/>

        <field name="implied_ids" eval="[(4, ref('group_mymodel_officer'))]"/>      

    </record>

    <record id="group_mymodel_officer" model="res.groups">

        <field name="name">Officer</field>

        <field name="category_id" ref="mymodel_category"/>      

        <field name="implied_ids" eval="[(4, ref('group_mymodel_user'))]"/>        

    </record>

    <record id="group_mymodel_user" model="res.groups">

        <field name="name">User</field>

        <field name="category_id" ref="mymodel_category"/>

    </record>    

</odoo>

I'd succeed when upgrading the module.

But when install the module in (UI), I got an error like this:

Odoo Server Error
