Gateways control how the process flows. They define interactions between sequence flows in a process.
The following types of gateways are supported:
Exclusive
Parallel
Note:
Sequence Flows Emerging from Gateways
In this release, only sequence flows emerging from gateways can have expressions. Only one path is taken, the first one whose expression evaluates to true. If no path evaluates to true, the default path is taken.
