Hi everyone!

I have created a new group for "limited salesman", which can view less informations than the default salesman group. The main definition of my group is:

<record id="group_sale_limited" model="res.groups">
    <field name="name">Group for limited salesman</field>
    <field name="comment">[...]</field>
    <field name="category_id" ref="base.module_category_sales_management"/>
</record>

Now, i would like this group to be added as an "implied" group for the existing salesman group (so, users added to the base salesman group would also be added to my custom group). I'd like to do this in XML, by i haven't found a way to do it so far. Here is what i tried:

<record id="base.group_sale_salesman" model="res.groups">
    <field name="implied_ids" eval="[(4, ref('my_module.group_sale_limited'))]"/>
</record>

But this doesn't seem to work, as the base.group_sale_salesman doesnt have "group for limited salesman" in its "inherited" tab.

ow, i know that i could manually add it, and i could also do it in python, but then i couldn't ensure that the group is correctly added when the module is installed....Could anyone help me doing this?
Thanks a lot!
