Hi,

I followed the documentation and I had trouble using the same form when editing my object.

Since the third attributes $data of createNamedBuilder() is @param mixed $data The initial data,
should we not give him a Food instead of meal ?
Check my PR.

In order to handle edition using the same form, I also edited the LiveComponent.
With this, to call the component we need to pass attributes (but it's not on this page of the documentation).

{{ component('MealPlanner', {
    form: form,
    mealPlan: mealPlan.id ? mealPlan : null,
}) }}

Imho, this might be a good idea to add it to the documentation too (I found mealPlan: mealPlan.id ? mealPlan : null in an issue...)

Thanks

Hi there!

Apologies for the slow reply on your PR :). Actually, it's a nice change - but I had, by coincidence, just 1 day after this PR, refactored that class to use symfonycasts/dynamic-forms. Hopefully I've not introduced any new mistakes in that PR ;).

Thanks!
