Salesforce Facts by Abhishek

Suppose we have a requirement that a radio button needs to be selected by the user in the current screen. Once the user moves previous/next from the current screen, it should get disabled. We can implement this using screen action and bit of condition logic. We can add condition to make sure the screen action autolaunched flow is called only once. And we can create a formula resource to check the InProgress and IsSuccess property of the action button which is used in the disabled attribute of the radio buttons. Attached are the screenshots.

Suppose we have a requirement to keep track of the first selected radio button in screen flow. For this, we can create an autolaunched flow and call it as a screen action. This flow will accept the first selected value and assign to a variable. We also need to set the action run condition in a way so that the subflow is called only once. In this example, we have a radio button with three values: Option1, Option2, Option3 and in the action run condition we have specified to call this flow till the currentValue resource is null. Attached are the screenshots.
