Description

Use the Exclusive Gateway to model a decision in the process. The process will continue with the sequence flow where the defined condition is "true".

  • If you use an exclusive gateway, only one sequence flow is selected. If the conditions of several process flows evaluate to "true", the first one is selected to continue the process.
  • If no condition is evaluated as "true", the result is a runtime exception unless you have defined a default flow.
