Calling method in custom field type

I'm trying to create a new custom form field and I'm wondering if there's a way to call a method from the component class. For example, if I have the following form field

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
        <button wire:click="doSomething">Click me!</button>
    </div>
</x-dynamic-component>

<x-dynamic-component
    :component="$getFieldWrapperView()"
    :field="$field"
>
    <div x-data="{ state: $wire.$entangle('{{ $getStatePath() }}') }">
        <button wire:click="doSomething">Click me!</button>
    </div>
</x-dynamic-component>

and the class

class MyCustomComponent extends Field
{
    public function doSomething() {
        // Nothing useful
    }
}

class MyCustomComponent extends Field
{
    public function doSomething() {
        // Nothing useful
    }
}

I get the following error Unable to call component method. Public method [doSomething] not found on component The method obviously exists, but I think it's because the dynamic component doesn't really know where to look. Ss there a way to call the custom doSomething() function in a dynamic component?

+1 I can add that in my case, the component receiving the call is the Widget, not the Column. If I create a dummy doSomething() function in the widget definition class, the error disapears. Yet, it is useless!

Form components aren't Livewire components, therefore your method cannot live in the custom field class. You have two options: 1. Add the method to the page (ListRecords, ViewRecord, CreateRecord, EditRecord) 2. Use events instead of methods. See how its done in https://github.com/search?q=repo%3Asaade%2Ffilament-adjacency-list%20builder%3A%3Asort&type=code

Linking to a code search like this is super clever! Will surely make use of that in the future 👌

Yeap, I also asked in the discussions forum and Events seems to be the best approach. Here is the discussion link: https://github.com/filamentphp/filament/discussions/8865
