Example

Click to play the following video that shows an example of using a calculate node in an actionflow.

View file
nameOpen Calculate Example.mp4
height250

Initially there is

The video shows  an actionflow

which

that opens a new screen containing a dynamic text field.

The aim of this example is to populate this

It then populates the dynamic text field with a message, which is set

by an attribute

in a calculate node attribute. The steps for

this

are:

Create a  Insert excerpt_action_calculate_action_calculatenopaneltrue node by dragging and dropping a node from the create section in the toolbar
  1. Drag a calculate node from the toolbar and drop it into the actionflow diagram.
  2. Name the calculate something meaningful, e.g. Set Message
  3. Disconnect the
    Insert excerpt
    _action_screen
    _action_screen
    nopaneltrue
     node from the 
    Insert excerpt
    _driving_interface_connection_point
    _driving_interface_connection_point
    nopaneltrue
    .
  4. Connect the 
    Insert excerpt
    _driving_interface_connection_point
    _driving_interface_connection_point
    nopaneltrue
     to the 
    Insert excerpt
    _action_calculate
    _action_calculate
    nopaneltrue
     node.
Connect the  Insert excerpt_action_calculate_action_calculatenopaneltrue to the  Insert excerpt_action_screen_action_screennopaneltrue node, using Create a calculate attribute
  • Name this Message
    • Add the following expression
    1. To pass data into the actionflow, go to the Inputs section on the left. Connect the component input connection point
    - 'ScreenToOpen'. This is the name of the outermost area/form on the screen, enabling data to be passed to it.
    1. ScreenToOpen to the calculate node.
    2. Click on the calculate node to open its properties.
    3. In the Attributes section, add a new calculate attribute and set:
      1. Name to Message

      2. Expression to:

        Code Block
        "You have successfully set up a calculate node"


    4. Map the calculate attribute to the dynamic text field on the
    screen 
    1. screen as follows: 

      1. Right-click on the connection and click Configure Mappings.

      2. Drag the Message attribute from the calculate
    (LHS)
      1. node, on the left, to the Message attribute on the open screen
    (RHS)
      1. , on the right.
      2. Close the mapping screen.
    2. The actionflow configuration is complete.

    Calculate Attributes

    Calculate actions process data using expressions; see pages in the topic Expressions and PhixScripts.

    This section has a toolbar with standard buttons. The grid contains a list of the expressions that the calculate action will perform. 

    • To add a new expression, in the section toolbar click 
      Insert excerpt
      _add
      _add
      nopaneltrue
       to open a new expression and set the properties.
    • To edit an existing expression, double-click it in the list to open its properties.
    • To remove an expression, select one and in the section toolbar click 
      Insert excerpt
      _delete
      _delete
