Something really strange is happening and I am not able to resolve it using the

Is it pausing at the 1st OR gateway or the 2nd? You need to add the dummy script task before the 2nd OR gateway too as it has multiple input flows.

Thanks for your response Tim.
I have added a script task before the 2nd also but this didn't work. Strange though since the second OR had only one incoming flow.....

Sorry I confused your OR's and XOR's! Are you certain it's stopped at the 2nd XOR? I can't see the green highlight. Based on your diagram I would expect it to pause 2nd time around at the 2nd OR gateways as it has 3 incoming flows.

I recommend reading the "Notes" section of the documentation on gateway nodes - forum.appian.com/.../Gateways

Everything is working now. It was something caused by another node. Thanks for thinking along.

I am having the same issue with the XOR. How did you fix it? Does the OR node have the same issue?

My process hangs the 2nd time it enters the XOR node.

@Leslie - You're likely experiencing this:
"If one of the incoming paths to a gateway has not been activated and the process flow reaches the same gateway again through a loop, the process does not proceed past the gateway. This is because all input paths from the first instance of the gateway have not yet been activated."

If so, create a dummy script task node before the XOR to merge all the flows so that the XOR only takes one input.
