I drag a XOR gateway into the line ,and I want to assign a Boolean parameter to control the gateway .
But I can not find the setting function ,
So how to use the XOR gateway to determine where the process go in the next step .
First thing you have to do is make sure the XOR is pointing to TWO (or more) second steps...if there is only one the condition will not appear.
Then In the details pane under general you can add the Condition as to where the flow goes.
