Undefined variable $activeManager on relation manager custom view

Hi,

I tried copying the view from filament-panels::components.resources.relation-managers to a new view filament-panels::components.resources.relation-managers-custom and set it as the view on my relationship manager. but for some reason I got this error message when I loaded the page

Undefined variable $activeManager

anyone has any idea about this?

The error message "Undefined variable $activeManager" suggests that the variable $activeManager is not being passed to your custom view. When you copy a view and customize it, you need to ensure that all the necessary data is being passed to the view, just like it was in the original.

Here's how you can resolve this issue:

Check the Original View: Look at the original view filament-panels::components.resources.relation-managers to see how the $activeManager variable is being used and passed.
Pass the Variable to Your Custom View: When you set up your custom view, make sure that the controller or component that renders this view is passing the $activeManager variable to it. This is typically done in the method that returns the view.

Example Code: If you are using a controller or a component to render the view, it might look something like this:

public function render()
{
    $activeManager = $this->getActiveManager(); // Example method to get the active manager

    return view('filament-panels::components.resources.relation-managers-custom', compact('activeManager'));
}

Ensure that the method getActiveManager() (or whatever method you use) correctly retrieves the $activeManager data.

Check for Typos: Ensure there are no typos in the variable name in both the view and the controller/component.
Debugging: If you're still having issues, you can use dd($activeManager); before returning the view to ensure that the variable is being set correctly.

By ensuring that the $activeManager variable is correctly passed to your custom view, you should be able to resolve the "Undefined variable" error.

@aarontharker this is the exact same code from the /resources/views/vendor/filament-panels/components/resources/relation-managers.blade.php
