Hi,

I have a model and a tree view defined for listing all the entrys. Now I want to have a button in this tree view and when I click on it a popup should be opened and show specific data from the entry that has been clicked on, similar to a tree view in a notebook page in the models form view.

This is my model:

class Paper(models.Model):
    _name = 'paper_submission.paper'
    _rec_name = "title"

    title = fields.Char(string='Title', required='True')    
    review_ids = fields.One2many('paper_submission.review', 'paper_id', string='Reviews')

The tree view:

<record id="paper_submission_paper_tree" model="ir.ui.view">
    <field name="name">Paper List View</field>
    <field name="model">paper_submission.paper</field>
    <field name="arch" type="xml">
        <tree>
            <field name="title"/>
            <field name="state" invisible="1"/>
            <button string="Assign Reviews" type="action" attrs="{'invisible': [('state','!=','submitted')]}"/>
        </tree>
    </field>
</record> 

When I click on the button I want to have a popup tree view where I can create new reviews and list the currently available reviews like this:

<record id="paper_submission_assigned_review_tree" model="ir.ui.view">
    <field name="name">Assigned Review Tree</field>
    <field name="model">paper_submission.review</field>
    <field name="arch" type="xml">
        <tree create="true">
            <field name="reviewer_id"/>
            <field name="avg_grade"/>  
    </field>
</record> 

How can I achieve this?
