Input.ChoiceSet changeAction

Description

Open Issues

• Confirm how this may be impacted with other inputs. DECISION: Might be weird with Input.Text, but we can cross that bridge when we get there.

• What about setting focus on an element, etc. Perhaps an action collection design. DECISION: Not at this time

• Can we allow a per-choice action? DECISION: Not at this time.

• Do we need to delineate between server-side and client-side variations? DECISION: Server-based actions only for now

• What is the final name if we do decide to delineate? DECISION: changeAction because it would work for Toggle.

Schema/spec

Property
Type
Required
Description
changeAction
Action
No
When specified, an the Action will be executed when a choice is made. Only supports Action.Submit and Action.Execute

Requirements

1. This property only works when isMultiSelect is set to false

2. Should work for any style (radio buttons, and drop downs)

Examples

{
   "type": "Input.ChoiceSet",
   "label": "Select a user",
   "isMultiSelect": false,
   "choices":  [
      { "title": "User 1", "value": "User1" },
      { "title": "User 2", "value": "User2" }
    ],
   "changeAction": {
      "type": "Action.Submit",
      "id": "userSelectAction"
   }
}

The issue names Input.ChoiceSet and its changeAction property but provides no implementation files, tests, or renderer entry points. Start by tracing Input.ChoiceSet schema and renderer handling, then determine how the stated single-select and style requirements are covered. Done means the schema and documented behavior support the specified server-side actions.
