TYPO3 Core

Using the inverse (always enabled, disable on specific conditions) is no option for me, because I want to disable it in every finisher and step Type, except Page! So I can not just query for 'stepType == "SummaryPage" || finisherIdentifier in ["EmailToSender", "EmailToReceiver"]' because this would enable it in custom finsishers and custom page types that are not explicitly in this exclusion-list.

In FormRuntime::getConditionResolver, called by processVariants(), I see this:

$page = $this->getCurrentPage() ?? $this->getFormDefinition()->getPageByIndex(0);

So, even in finishers you are basically on a stepType "Page". And for the "SummaryPage" this happens because processVariants() is also called from initialize(), but BEFORE the currentPage is initialized.

This means:

processVariants() is always executed twice. Always at initialize() ( before the current stepType is known and falls back to Page then) and then either when rendering (on summary page it is then "SummaryPage") or when finishing (it is then "Page"). But the first initialize() call already makes stepType == "Page" always true in any case.

My current workaround is this: field always enabled, but disable on non-Page steps and when any finisher is executed. This seemingly covers all cases, but you never know. Having it work "forward" instead of "backwards" would be better.

variants:
    - identifier: showOnlyOnPages
      renderingOptions:
          enabled: false
      condition: 'stepType != "Page" || finisherIdentifier != ""'
