you can use this,

see this link: https://github.com/odoo/odoo/blob/9.0/addons/account/models/account_bank_statement.py#L213

return {

'type': 'ir.actions.act_window',

'name': 'view_tree_label_picking',

'view_type': 'tree',

'view_mode': 'tree',

'res_model': 'label.picking', 

'context': {},

'target': 'new',

}

in context you can pass the current object id or in context itself have the active_id and active_model in pop wizard

[UPDATE] Despite some colleagues have tried to answer I am still not being able to move the ID from the form to the wizard transient model. I am missing something, thanks anyway for your help. Anyone willing to give a more detailed solution please do, as this not solved yet.

hi, 

Reference to this post: 

https://www.odoo.com/es_ES/forum/help-1/question/developing-a-new-popup-in-stock-picking-basic-doubts-about-how-to-generate-the-popup-97625

with that question I have also fought x-D with this code:

   context.update({ 'tipo_entrega' : 'ok_con_incidencias', 'delivery_line_id': value that you want, }) 

record_id = context.get('delivery_line_id') ( see -> #modelo temporal para popup.)
