Uncaught TypeError: self.groups.get_row_for is not a function

[Monasha1992]

I installed both 'many2many_default_data_demo' and 'many2many_handle_widget_demo' modules. When I clicked on a item on 'Many2many handle demo' page Item , is shows a JS error like shown below.

@Monasha1992 I haven't seen this one before. What browser are you using? Which Odoo version is this?

[Monasha1992]

Thanks for the quick reply. This is Odoo 8 on Chrome browser version 49.
This happens to me every time when I click on a editable many2many tree view. Ps. Tree view data was loaded on default.

@Monasha1992 I'm actually not sure how you get this errors. I've tested this on my V8 and they don't give any problems at all..
Is your V8 very old or something? Can you also try it in another webbrowser such as Firefox, just to be sure it is not some new Chrome issue or something.
