Behavior Tree question

Is it possible to create a BT decorator in blueprints that work similar to “Blackboard check” but for some other condition not in Blackboard? I try to do it using “event receive condition check” and “finish condition check” nodes, but the event only fires once at the beginning. Therefore, my decorator can never abort anything.

In my case, I want to check that an actor is in some particular state. I have reference to the actor in BB and my conditional decorator is simply checking the state of this actor, setting “allow execution” parameter accordingly. The actor can also fire an event when its state changes.

Can anyone give me an example of such blueprint?
