Single zone with multiple entry point

I'm trying to restrict the number of tokens with in an area (I can only have one token at any point of time). Since I have to destroy an object and send it to the sink, I'm not able to continue with the zone and the token has to exit the zone. I was checking to see if I can continue with the same zone after the new object is created but looks like they are considered as two different areas and I end up having 2 tokens. In the image attached is there a better way I can have only one token flow through the area highlighted.

Hi @Rohith V,

I think there is a way to do what you are asking, but I need to understand a little more about your process. For example, do you have to sink the token after you destroy the object? Could you simply destroy the object then immediately create a new one while the zone is acquired?

Hi Ben,

Yes, I have tried without a sink and it works since its a single loop. I was looking at a different option of adding a sink and wondering if there was a better way of limiting the number of tokens.

Hi Jeanette,

I'm curious to know if I can use a zone when there is a sink involved? As shown in the screen shot with my initial post, can I make a zone to work when there is token sent to sink and a new token is created which is linked to the previous activity?

Hello @Rohith V,

For your process flow block on the left, is Event Triggered Source linked to the process flow block on the right? If so, then you could assign the a label in the Event Triggered Source to the token in the right block. This will allow the token on the left to exit the zone as a proxy for the token from the right process flow block.

I created a small example process flow for you to reference.

Zone exit as proxy.fsm

Update: also any wait for event activities between the two blocks of activities can create a label that assigns the token.
