This page provides details of the properties for the 
Gateway action node, which is part of an actionflow.
Overview
Use a gateway node to control the path that data records take as they flow through an actionflow. You can add several input or output connection points. On the output connection points, you can specify decision logic to control the path of data, record by record.

Output Connection Points
This section has a toolbar with standard buttons. The grid contains a list of all output connection points. Each output connection point has an expression that specifies the logic to control whether or not records flow to the next action node.
For driving output connections, you can refer to an attribute in the expression using the syntax:
connectionpointname.attributename
| Field | Description |
|---|---|
| Exclusive | Used to control if a stream-item can flow through more than one option. Todo-Fiona - Where does this property appear?

Output paths process data using expressions; see pages in the topic Expressions and PhixScripts.
Gateways can have an unlimited number of output paths.
Stream-items will only pass through the output paths if the condition set in the expression is met.
Remember to check if if the gateway has been marked as Exclusive. Records will only pass through the first output path where the condition is met if the gateway is exclusive.
This section has a toolbar with standard buttons. The grid contains a list of output connection points and their expressions.
- To add a new output path, in the section toolbar click Add New to open a new output path and set the expression.
- To edit an existing output path, double-click it in the list to open its properties.
- To remove an output path, select one and in the section toolbar click
Permanently Delete.
The expression properties has sections for Parent Details , Audit Summary and the following Basic Settings:
Field | Description |
|---|---|
| Name | Enter an expression name. |
| Order | Where the gateway action runs and expression for each output path, enter a number to indicate the order in which this expression will be run. Remember that an expression that generates a value should run before an expression that uses the value. The order is especially important if the gateway is marked as exclusive. |
| Expression | Enter an expression which evaluates to true or false to determine if stream-items will pass through this connection point. To work in a larger pop-up window, click See also: |
