shop_selection = fields.Selection(_get_radio_button, string="Shop Action")

I am using _get_radio_button() function to load the radio button values as per conditions.
Context gives correct values other functions.

But when using same context code in the _get_radio_button() to get the currently active id of the sale_order,
it just return empty in Odoo17 for me.

You have to pass context for sale order id in the action from where you are open a wizard and then you can use this context value in your relative method of wizard.

I tried passing sale order id in context of the action that calls the wizard. But the data not getting inside the _get_radio_button() function.
In other functions like default_get(), I can access the context data.

Please paste the opening wizard method code here.. If I'm not wrong you're opening that wizard sale order, Right?

I am opening the wizard from the sale order actions. Above code is the wizard code.

when printing action i get below result in log.
context data is getting in the default_get().
Not in the _get_radio_button() function which used to return radio button list as per condition.

sale_ids = fields.many2many()

@api.model
def default_get(self, fields):

res = super(TestOrderShop, self).default_get(fields)

selected_ids = self.env['sale.order']._context.get('active_ids', [])
res['sale_ids'] = [(4, selected_ids)]
_logger.info('\n\n\n\n selected_ids = %s \n\n\n\n' % (selected_ids) )

return res

You can use sale_ids in radio button method.

I tried similar and this method. But seems _get_radio_button() function is calling before the default_get() function.
So in log the variable value showed unknown in _get_radio_button() function.

selected_ids = _unknown()
