Expression

The expression edge controls sequence flow based on a Javascript expression.

"Expression" is a Javascript expression that must evaluate to "true" for the edge to be followed. In this example, the variable "i" must be less than 10.

All edges can be used to set or modify variables when the edge is followed. This is done in the "Variables" tab. The same convention for setting variables in a trigger is used. See See Passing Variables with Triggers for more information.
