getMountedTableActionRecord() returns null in RelationManager (EditAction)
I'm building a RelationManager for MenuItem -> VariationGroups, where each variation group has multiple options, and each option has multiple ingredients. This is a nested repeater structure (options → ingredients), and I want to load existing nested data into the form when editing.
I’ve already implemented mutateFormDataBeforeFill, but it’s not being called when I click the Edit action on the relation manager. I tried adding a custom mount() method and manually calling $this->form->fill([...]), but even then, getMountedTableActionRecord() returns null.
My data saves correctly, but my problem is only on the form preloading (not saving).
What I've Tried?
Implemented mutateFormDataBeforeFill() → not triggered
Tried mount() override → getMountedTableActionRecord() returns null
Tried using ->default(fn () => $this->loadOptions()) in the Repeater → but it only works on create, not edit
Verified data exists (the group, options, and ingredients are loaded properly)
Code Context
Using RelationManager, nested repeaters like this:
Repeater::make('options')
->schema([
// ...
Repeater::make('ingredients')->schema([
Select::make('inventory_item_id'),
TextInput::make('quantity'),
Select::make('unit'),
]),
])
What I Need Help With?
What’s the correct way to preload nested repeater data inside a RelationManager?
Why is mutateFormDataBeforeFill() not firing when editing a relation row?
Is there a better hook than mount() for injecting default form data when editing?
