Overview

Use the input and output connection points on nodes in an actionflow to wire the nodes together.

From the Inputs pane on left, into the actionflow.
From one node to another within the actionflow.
Hover your mouse pointer over a node and click Add Output to add an connector to another node.
From a final actionflow node to the Outputs pane on the right of the actionflow.

Connection points available depend on the purpose of the node.

Output connection points:
- Calculate
- Gate
- View

Nodes without an output connection represent:

either the end of actionflow processing: Save Action Configuration, Open Screen and Action Configuration and Open URL nodesAction Configuration
or processing out of the actionflow: Analysis node.Action Configuration

When you wire nodes together, you need to map which attributes pass through to the next node. To change the mapping, click on the connector to open the Mapping window.

Node properties have sections for Input Connection Points and Output Connection Points on the node. Double-click on a listed connection point to open its properties.

Note
The properties available for connection points vary depending on the node on which they occur.

Driving and Lookup Connection Points

If you connect a node via a driving connection, records are returned individually to the connected node and flow one by one through the remainder of the actionflow.
If you connect a node via a lookup connection, the records are returned as an array within one recordset. Nodes wired via lookup connection points require both:
- Data Attributes: add attributes from the view. PhixFlow looks-up data from these attributes.
- Request Attributes: when the actionflow runs, PhixFlow returns the data to these attributes.

The following sections explain the properties for input and output connection points.

Default Value

Available in PhixFlow 11.1.1+

A value or expression that is evaluated when no value is mapped to the attribute, or if the value is null or unavailable (e.g. if the user did not have permission to see it).

For referencing attributes, use the notation in.attributeName.

Note: Default value expressions do not use the order they are set in and are automatically resolved in the appropriate order based upon other attributes they reference.

Input Connection Points

See Input Connection Points.

Input Connections

A grid of Input Connections.

The following properties are available for Input Connections for open Screen Action nodes only.

Field

Description

Role

Specify whether the actionflow will provide data to the view or screen being opened.

Primary: selected by default.
The view or screen opens regardless of data.
Component:
The actionflow provides data to the view or screen when it opens.

Type

Available when Role is Component.

Specify the type of connection:

Insert excerpt
_driving_input_connection_point
_driving_input_connection_point
nopanel true
: there can be only one of these.
Insert excerpt
_request_input_connection_point
_request_input_connection_point
nopanel true
: there can be multiple of these

Open Mode

Excerpt

name	screenInputConnections

Available when Role is Component. For example,

When a screen opens, specify how data fields will display:

Insert data fields are cleared and variables are passed to the screen from the actionflow, the screen is then ready for the application user to add new data. Typically used for adding new data.
Update Variables created in the actionflow are set on the screen, any filtering is applied, data is retrieved from the server and displayed in the fields. Note the values set by the actionflow are persisted. Typically used for updating existing data.
Change Fields Variables passed to the screen are set. Typically used to set a value on one screen from another.

Attributes

A list of attributes available on the input connection point. These directly link to the fields available on the form.

Primary connection points display the screen properties as attributes.
Component connection points display attributes available on the associated form.

HTML Comment

Not yet implemented - and may need to be on the input connection page.
Each open screen node has 1 primary input connection point by default called 'screen'. Available when Input connection point Role is Primary, optionally set:

Field	Type	Default Values if not set	Description
Height	Number		Sets the height of the screen
Width	Number		Sets the width of the screen
Top	Number		Sets the top position of the screen relative to the window
Left	Number		Sets the left position of the screen relative to the window
Maximised	Boolean	whatever is set on the screen properties	True will open the dashboard in its maximised state. False will open the dashboard in its minimised state and will use the above properties.

When you connect an open screen node to a screen, PhixFlow automatically adds an input connection point for each form on the screen. The input connection point is automatically set to:

Role Component.
Attributes: all data fields and dynamic text fields are added.
This means you can map to the attributes and pass data to them.

Data Attributes

This section has a toolbar with standard buttons. The grid contains a list of the attributes that will pass through the wire into this node. All nodes can have a driving input connection, which passes data records one-by-one into the node.

To refer to these attributes in an expression, specify the names of the connection point and attribute with the syntax:

Code Block
connectionpointname.attributename

Double-click on an attribute in the list to display tje properties related to this node and connection. This can include Name, Type, Component, Primary Key etc.

To create a new attribute: click
Insert excerpt
_add
_add
nopanel true
and set the Name and Type; see Attribute.
To add an existing attribute to this list, open the list of attributes and drag one onto the grid.
To open its properties, double-click one of the listed attributes.
To remove an attribute, select one and click

Request Attributes

Available for View, Gate and Calculate nodes, which can have Lookup connection points.

This section has a toolbar with standard buttons. The grid contains a list of the attributes that you want to lookup from another table. Lookup connections pass a complete set of records into the node.

To refer to these attributes in an expression, specify:

Code Block
req.attributename

Double-click on an attribute in the list to display its properties related to this node and connection. This can include Name, Type, Component, Primary Key etc.

To create a new attribute: click

Output Connection Points
Anchor
output
output

This section is not available for nodes that do not require output connections because: the node represents the end of actionflow processing: Save, Open Screen, Open URL, and Analysis nodes.

For all other nodes, the output connection point has an expression that specifies the logic to control whether or not records flow to the next action node. The syntax for a driving connection is:

Code Block
connectionpointname.attributename

The syntax for a lookup connection is:

Code Block
req.attributename

If the expression evaluates to true for the record flowing through the node, it will pass through the connection point onto the next node in the sequence.

Field

Description

Name

Enter a name for the output connection point

Order

Enter a number to indicate the order in which this expression will be run.
Remember that an expression that generates a value must run before an expression that uses the value.

Tip
The order is very important for exclusive gateway nodes, as the records pass through the first output connection that meets the expression condition.

Expression

Enter an expression that evaluates to true or false to specify whether or not records pass through this connection point. To work in a larger popup window, click
