If you give condition like the above picture, for admin it won’t work.
When you login as admin , it will check whether current object owner is current user or not [Now current user is admin obviously admin will not be owner for that object] .
So, to make that button visible for both owner and admin. Create two buttons- add condition visibility for owner in one button and select the module role admin for other button.
In addition to above:
with user demo_user or demo_super user: than button A is shown ONLY of they are the owner (so that's ok)
with user demo_administrator : button B is shown in case the object owner is demo_superuser or demo_user (so that’s ok)
with user demo_administrator : button A and B is shown in case the object owner is demo_administrator (so that’s NOT ok)
only 1 button is what I want.
A bit late,,,
What you suggested works fine Steffy.
