Action Container behaviour is mainly used for resourcing tasks. Action Container can only be used with Python script. Action container has 2 lists, a list of Actions it supports and list of pending actions (like a work list).
To connect a component with a resource manager, you will need to have OneToOne or OneToMany interface which is an abstract interface. That interface hass a Action field sections and it uses Action container.
Remember to connect the Action container to a python script that will then react to the event when Action container sends a completed signal after each task.
