Extracting Actions

Action nodes, within an Actionflow, can be re-used by extracting them from their original Actionflow and converting them into a new Actionflow. In the original Actionflow, the actions are transferred to an embedded Actionflow node.

The newly created Actionflow automatically contains:

• input, output and lookup connection points to connections outside of the new Actionflow, e.g. to action nodes and the original Actionflow
• all transferred action nodes 

• the original attributes, which are mapped to match the original Actionflow setup

Creating a Reusable Actionflow

1. To make a reusable Actionflow, select the required action nodes and right-click to choose  Extract to new Actionflow
   
   1. A new Actionflow is automatically created
      
   2. On the original Actionflow, the selected action nodes are replaced with the new embedded Actionflow node - see Actionflow Node
      

Worked Example

Here's a worked example using the Shop Data (available from the Learning Centre).

In this example, we are using:  

• A Customer Form screen containing blank input fields, set up to create a new staff member  - this screen was created using the Edit Form template

Extract Proper Case Calculate Action

In this example, we'll modify the Actionflow on the Save button for when a customer is created. We'll configure this Actionflow to convert the string entered for the First Name attribute to proper case, for example, if the user enters "JOHN" or "john", this action will convert this string to "John". 

We'll then extract this Actionflow and use it on the Save action on the Staff Form.

Create Proper Case Calculate Action

1. Open the Actionflow on the Save button on the Customer Form
2. Add a  Calculate Action
3. Drag the Calculate Action onto the connector between the input and Save action
4. Click on the input connector under Connections and map in the first_name and last_name attributes
5. Map these two attributes into the Calculate action
6. Create a new Output Attribute that will convert text to proper case, using the following Expression
   
   Expression

   do(
   
       // put the name into lowercase, e.g. "john"
       toLower(in.first_name), " ", 
           
           // put the first letter into upper case, e.g. "J"
           $firstLetter = toUpper(substring(in.first_name, 1,1)), 
               
               // put the name from the 2nd letter onwards into lower case, e.g. "ohn"
               $remainingLetters = toLower(substring(in.first_name, 2)), 
                   
                   // create a new proper case name using the upper case first letter and lower case remaining letters, e.g. "J" + "ohn" = "John"
                   $newName = $firstLetter+$remainingLetters
   )

7. Click on the connector between the Calculate action and the Save action

8. Map across the new Output Attribute onto the first_name attribute

9. Close the Actionflow and Customer Form
10. Reopen the Customer Form and enter a First Name in upper or lower case, then press Save to test the Actionflow

Extract Proper Case Calculate Action

1. Re-open the Actionflow
2. Right-click on the Proper Case Calculate Action and choose  Extract to new Actionflow
3. Name the Actionflow: Proper Case
   1. This Actionflow can now be used elsewhere in your application

Embed Extracted Action in Actionflow

1. Open the Actionflow on the Save button on the Staff Form
2. Click  Actionflow in the toolbar and drag the Proper Case Actionflow from the Repository
3. Drag it onto the connector between the input and Save action
4. Choose the out_ProperCase connection point from the Select Connection Point pop up
5. Click on the connector between the Proper Case and Save action
6. Map across the ProperCase attribute from the embedded action node to the firstName attribute on the Save action
