text handling rules
•
list handling rules
•
looping
More complex boolean rules can be built using multiple rule components.
For example
If id = 10 AND name = "Jones”

id = 10
and the
second as
name = “Jones”
.

Triggers
Certain types of event - including loggable events and Java exceptions - can be handled using
triggers
. These are (typically short) alternative dialog flows that are run when the triggering event
occurs.
There are five types of trigger:
•
Exception
- evaluated only when an exception occurs in the underlying code
•
Before step validated
- legacy feature. DO NOT USE
•
Before step runs
- evaluated before the step
•
After step runs
- evaluated after the step
•
Unhandled control
- evaluated if the path required is not defined in the dialog flow
