Using the No Data Result Path

  • Print

If a flow step requires input that is not provided, the flow will stop running. For example, if a step requires input data from a user-completed form and the user submits the form with no data in the required fields, the flow will not continue. Adding a No Data Result path solves this problem by allowing a flow to proceed, even when a flow step requiring input does not receive it.  
Add a No Data Result path in the Flow Designer by selecting the Show No Data as Path checkbox in theProperties panel, under the Outcomes section.

Example

In this example the flow will capitalize text that we will supply via a form.

If the form is submitted without text, we will be presented with another form advising us to add text for capitalization. Behind the scenes, our example flow has continued to the End Step .

We begin our example with the bulk of our flow already in place. Our first step is the form into which we'll enter text for capitalization. It has one path Capitalize that flows to our capitalization component Capitalize 1 . This step also has one path  Done which leads to the End Step. Another form End Form 1 has also been previously created for this example.
In the event that our form is submitted without text, we want Capitalize 1 to detect this and show us the second form. Select Capitalize 1 and, in the Properties panel, under the Outcomes section, select the Show No Data as Path checkbox. This creates a No Data Result anchor which we can use in the next part of our example.

Next, place the form that will alert us when we've submitted our first form without data.
In the Toolbox panel, under the categoryForms [End] , drag anEnd Form component to the workspace.  
Next, we'll connect Capitalize 1 to [Form] End Form with the No Data Result path. Also connect**[Form] End Form** to the first form with the Done path. This completes our flow.

Click Debug Flow to run this flow in the debugger.

Click the Diagram tab to see the flow's progress.

Even though we entered nothing in the field on the form, the flow has continued to run, reaching theEnd Step , directed in part by the No Data Result path.
Close the debugger and run the flow.

We're directed to our second form, telling us that we need to provide text to capitalize.
