Hi,

I have a wizard which appears after I click a button in a Purcahse Order template. I want to populate dropdown in the wizard with the respective Products in the purchase order line. Sometimes I get 'resursion depth error' and sometime 'expected singleton error'

model.py file:

order_line = fields.Many2one('purchase.order.line', 'Order Lines')

XML file:

<field name='order_line' widget="selection"/>
