📝 Walkthrough

Walkthrough

EventForm gains an isPresentation() helper that checks entity.class_name === "Presentation". The missingDraftFields computation in render() and the "save as incomplete" warning button in the submit-actions area are now both conditional on that helper, suppressing them for all non-Presentation event types.

Changes

Presentation-only draft UI gating

Layer / File(s)	Summary
isPresentation helper, draft fields, and save-incomplete button src/components/forms/event-form.js	Adds isPresentation() instance method checking entity.class_name; missingDraftFields now returns an empty list unless isPresentation() is true; the save-as-incomplete button now renders only when isPresentation() is true and the event is neither new nor complete.

Poem

🐇 A bunny hopped through the form one day,
And found the draft warning had gone astray —
It popped up for events of every kind!
Now "Presentation" keeps it well-confined.
Only the right type gets the caution shown,
The rest of the events may leap on their own! 🎉
