How to Handle Selection List Validation Issues in ScreenFlow?

In Salesforce ScreenFlow, you may encounter an issue where a Selection List field prompts an error message like “Please select one option” even when the field is not marked as required. This behavior can occur due to changes introduced in updates like Winter ’25, which may enforce stricter validation rules for certain components. Understanding how to handle selection list validation issues in ScreenFlow is crucial to maintaining smooth user interactions.

Question

Why does a Selection List in ScreenFlow show a ‘Please select one option’ error when not set as required, and how can I resolve it?

Possible Solutions

1.Set the Field as Optional in ScreenFlow Configuration:

Ensure that the Selection List field is explicitly marked as optional in the Flow Builder. While this is generally the default behavior, the field configuration might need adjustment. To do this:

• Open the Flow Builder.Select the problematic Selection List field.Verify that the “Required” checkbox is unchecked in the field properties.

<selectionList label="Select an Option" required="false">
    <option value="Option1">Option 1</option>
    <option value="Option2">Option 2</option>
</selectionList>

This code defines a Selection List where the required attribute is set to false. It ensures that the field will not enforce mandatory input, preventing validation errors when left unselected.

2.Add a Default Value to the Selection List Field:

Another way to handle this issue is by setting a default value for the Selection List field. This ensures that the field is pre-populated when the screen loads, preventing the error from occurring if no selection is made.In Flow Builder, assign a default value using a variable:

{!defaultSelection}

Here, {!defaultSelection} represents a variable containing the initial value for the selection field. This ensures the field is never empty, effectively bypassing the error.

3.Handle the Error Using Conditional Logic:

If the above solutions don’t work, you can use Decision Elements or Custom Validation Logic to bypass the error. For instance, you can add a decision node before navigating to the next screen to check whether a selection has been made. If not, redirect the user to the same screen with an appropriate message.Example:apexCopyEditIF({!selectionField} = null, "Please make a selection.")

IF({!selectionField} = null, "Please make a selection.")

This logic checks if the Selection List field is empty (null). If so, it displays an error message, prompting the user to make a selection before moving forward.

4.Use a Workaround with Radio Buttons:

If the issue persists and cannot be resolved with the Selection List, consider replacing it with a Radio Button Group. This component behaves similarly but may not encounter the same validation issues. Configure the Radio Button Group to allow optional input.Example:

<radioButtonGroup label="Select an Option" required="false">
    <option value="Option1">Option 1</option>
    <option value="Option2">Option 2</option>
</radioButtonGroup>

This code snippet creates a Radio Button Group where the required attribute is explicitly set to false. The Radio Button Group provides an alternative user interface for selection while mitigating validation errors.

Summing Up

To resolve Selection List validation issues in ScreenFlow, it’s crucial to ensure the field is properly configured as optional, with no required validation unless explicitly needed. Setting a default value or using variables to pre-populate the field can help avoid errors when no selection is made. Additionally, implementing conditional logic or utilizing a Radio Button Group instead of a Selection List provides effective workarounds to bypass validation errors. These approaches allow for a smoother user experience while maintaining the flexibility and accuracy of your flow’s functionality.
