This page provides details of the properties for the calculate node and associated expressions. These are part of actionflows.

Overview

Example

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

The video shows an actionflow that opens a new screen containing a dynamic text field. It then populates the dynamic text field with a message, which is set in a calculate node attribute. The steps for are:

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 nopanel true

    node from the 

   Insert excerpt
   _driving_interface_connection_point _driving_interface_connection_point nopanel true

   .
4. Connect the 

   Insert excerpt
   _driving_interface_connection_point _driving_interface_connection_point nopanel true

   to the 

   Insert excerpt
   _action_calculate _action_calculate nopanel true

   node.
5. To pass data into the actionflow, go to the Inputs section on the left. Connect the component input connection point ScreenToOpen to the calculate node.
6. Click on the calculate node to open its properties.
7. 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"

      
      

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

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

   2. Drag the Message attribute from the calculate node, on the left, to the Message attribute on the open screen, on the right.
   3. Close the mapping screen.
9. The actionflow configuration is complete.
