Hello :) 

I want to inherit the invoices form view in the accounting module to add the attribute "edit_multi"

But the view displayed is view_out_invoice_tree which only contains an xpath to add the attribute banner so i didn't know how to inherit it

I couldn't inherit the  view_out_invoice_tree because i couldn't find a way to inherit it

I tried to define a new tree view :

where i added the attribute banner and my attribute edit_multi

and override the  action_move_out_invoice_type by rewriting it in my custom module with id = account. action_move_out_invoice_type  and changed the ref on the field  view_ref to my custom view but this didn't work

Any ideas please  ?

Thank you very much.
