Filter on property of an entity in a many-to-one relation

[ToshY]

Describe the bug After not being able to find in the docs on how to apply a filter based on a property of the entity I'd like to ask if it's even possible.

To Reproduce As an example, I have have a many-to-one relation from User to Colour denoted with the property userColour. The Colour entity consists of a property colourCode which is of type string.

In the CRUD controller for User, let's say I have the following fields configured:

return [
    AssociationField::new('userColour'),
    TextField::new('userColour.colourCode'),
];

Now I can use the EntityFilter on userColour to filter (which works), but if I wanted to filter on userColour.colourCode it doesn't seem to be that easy.

return $filters
    ->add(EntityFilter::new('userColour')) // works
    ->add(EntityFilter::new('userColour.colourCode')) // doesn't work

Throwing the following error/stacktrace:

Error:
Call to a member function getAsDto() on array

     (vendor/autoload_runtime.php:29)
  at require_once('/app/vendor/autoload_runtime.php')
     (public/index.php:5) 

So am I missing something obvious here, either wrongly passing the property name or missing some options? Or is this either something that isn't working correctly, or maybe should a custom filter be used for such cases?

The dot is a known problem for filters for a while... :(

Still 3 options to filter embedded or association fields (with dot):

• (dirty) Custom filter to handle dot notation or nested field (#4120)
• (many) Redondant custom filters
• Entity update (omg)

@Ang3 Thanks for the reply. PR #4882 is still open, is there a reason not to merge that one?
