XOR gate struck when it comes the second time , any help would be appreciated !!
Got the same issue.
Quote from https://forum.appian.com/suite/help/16.3/XOR_Node.html
When multiple incoming flows are connected to the XOR gateway, it allows the first flow token through to an exclusive outgoing flow. Subsequent flow tokens wait for all incoming flows to arrive before executing the output flow decision.
NOTE: A looping flow should not be directed into an XOR gateway itself, but into another upstream activity.
For example, place an empty Script Task node between the incoming flows and the XOR node when you are routing multiple flows into the XOR.
So XOR can have multiple incoming flows but starting from the second time all incoming paths should arrive.
