Using a gateway to converge flows

Question

Hi there! I want to ask for advice for modeling processes in Appian. I'm trying to converge two flows in one gateway (you can find attached an example). My first try was using OR and Complex gateways but I got the same result for both of them. When the process flow arrives to the gateway for the first time, it continues normally but when the flow returns to this gateway after passing other user input tasks, gateways and script task, it stops. I have found a way to converge flows using an empty script task but I think it's probably not the better solution. In other BPM solutions, there are more types of gateway and usually they have one to converge flows. Are there in Appian any other ways to converge flows instead of using tasks? Thanks in advanced. 
 Regards

Hi Vctoro, 
Routing the flow to a dummy activity before the gateway is the only solution to this problem. 
For more details, you may refer the NOTE on this page:

Thanks

An empty script task is the normal way of doing this in Appian, due to the gateway limitations you've already discovered.

Due to limitations of Appian Gateways the only option is adding an empty script task node before the gateway.

Hi, 
Add dummy script task before gateway and pass all its input connections to dummy script task first and then from dummy to gateway. 
This is due to limitation of appian.
