TYPO3 Core

Given a form with conditional pages variants are not respected when the navigation is built. Example:

type: Form
prototypeName: standard
identifier: multi-step-form
label: Muli step form
renderables:
  -
    type: Page
    identifier: page-1
    label: First step
    renderables:
      -
        type: Checkbox
        identifier: checkbox-1
        label: Check this and the 2nd step will be skipped
  -
    type: Page
    identifier: page-2
    label: Second step
    renderingOptions:
      enabled: false
    variants:
      -
        identifier: variant-2
        condition: 'traverse(formValues, "checkbox-1") == 0'
        renderingOptions:
          enabled: true
  -
    type: Page
    identifier: page-3
    label: Third step
    renderingOptions:
      enabled: false
    variants:
      -
        identifier: variant-2
        condition: 'traverse(formValues, "checkbox-1") == 1'
        renderingOptions:
          enabled: true

Enabling the checkbox on the 1st page and going to the next page will show the 3rd page and a "Submit" button.

Not enabling the checkbox on the 1st page and going to the next page will show the 2nd page and a "Next Page" button. However, there is no next page here. In this case the button should also say "Submit".

The example above generally disables all subsequent pages and conditionally enables them which is a logical approach IMO. Especially because it allows you to have conditions which match their page 1:1. The reverse logic as suggested by the docs also doesn't work however:

type: Form
prototypeName: standard
identifier: multi-step-form
label: Muli step form
renderables:
  -
    type: Page
    identifier: page-1
    label: First step
    renderables:
      -
        type: Checkbox
        identifier: checkbox-1
        label: Check this and the 2nd step will be skipped
  -
    type: Page
    identifier: page-2
    label: Second step
    variants:
      -
        identifier: variant-2
        condition: 'traverse(formValues, "checkbox-1") == 1'
        renderingOptions:
          enabled: false
  -
    type: Page
    identifier: page-3
    label: Third step
    variants:
      -
        identifier: variant-2
        condition: 'traverse(formValues, "checkbox-1") == 0'
        renderingOptions:
          enabled: false
