Make Invocable Actions Easier to Configure with New InvocableVariable Modifiers

Simplify the configuration of invocable actions using new modifiers from Salesforce. Both the defaultValue and placeholderText modifiers will appear in Flow Builder for the Action elements that correspond to an invocable method. Here’s how to use them.

• defaultValue Modifier: Set a default value for an input parameter. When the action is used, the input parameter will have a predefined value unless changed by the user.
  

• placeholderText Modifier: Set custom placeholder text for an input parameter. Text can provide examples or additional guidance to help users understand what to enter in the input field.
  

Accessing these modifiers in Flow Builder makes it easier to configure and use the actions within your flows.

This change applies to Lightning Experience and Salesforce Classic in Performance, Unlimited, Developer, Enterprise, and Database.com editions.

Hand-On

Create a Class: MyIterable 

public class MyIterable implements Iterable<String> {

    private List<String> strings;

    public MyIterable(List<String> strings)

    {

        this.strings = strings;

    }

     

    public Iterator<String> iterator()

    {

        return this.strings.iterator();

    }  

}

Create a TestClass: MyIterableTest

@IsTest

public class MyIterableTest {

     

    @IsTest

    static void testIterableForLoop () {

         

        List<String> strings = new List<String>{'Hello','World'};

             

         MyIterable myIt = new MyIterable(strings);

        for (String str : myIt) {

            System.debug(str);

        }

    }

}
