I have following scenario

(a OR b OR c OR d) AND (e OR f)

I have built the following one:

<button name="close_ticket" type="object" string="Close Ticket" attrs="{'invisible': ['|','|','|','&amp;',('states','in',('waiting_approval','closed','draft')),('categ_id','not in',('support','payment')),('manager_appr','=', False),('payment_done','=', True),'|',('creating_user','=', False),('dep_user','=',False)]}" /> 

Its not working, as per me understandind, I am not applying AND at correct position.
