Version: FAB 5.0.1
The code does not reload the actions when going from related view to another and hence gives error as it could not locate the actions of the current view:
File "C:\Yahia\Python\FAB5\venv\Lib\site-packages\flask_appbuilder\views.py", line 306, in get_action_permission_name
self.actions.get(name).func.name
^^^^^^^^^^^^^^^^^^^^^^^^^^^
