Solved Event Handler - RIGHT_CLICK_AIR and RIGHT_CLICK_BLOCK errors

Solved: Found out that you need to check if the item from the main hand is being used.

Code:

if(e.getHand()== EquipmentSlot.HAND){
                if(e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK){
                    e.getPlayer().sendMessage("Event triggered");
                }
            }

Does have a solution for single trigger click only?

Code:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent e) {
   try {
     if(e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK){
       e.getPlayer().sendMessage("Event triggered");
     }
   } catch (Exception ex) {
     System.out.println("ERROR in onPlayerInteract method;");
     ex.printStackTrace();
   }
}

Player->looks at air->right clicks->Event Triggers once-> no error
Player->looks at a block (eye level)->Event Triggers Twince-> no error

My code seems to trigger twice when I click on a block but not on air?
