Hi All,
In one2many master line level, if i use reference field with selection field its throwing error like below,
<pre>
TypeError: Mixing apples and oranges: hr.employee(14742,).union(False)
</pre>
If i use only reference field (other selection field removed). its working fine.
Version : odoo11
ref_field = fields.Reference(selection=_select_models, string="Object")
can you please give some more details, _select_models ...etc any other related to reference.
Actually the error occurred because of reference filed referring data from two tables.
